Summary: This research numerically investigated the heat transfer and thermal performance in a pipe with hollow and perforated spherical turbulators. The effect of aerodynamic turbulators with the same blockage percentage was studied for increasing heat transfer and reducing energy consumption. The best performance was obtained with an oval hole turbulator of 1.26. The Nusselt number ranged from 1.58 to 5.02, and the friction coefficient increased by 3.55 to 13.99 times compared to a plain pipe in the studied geometries. The highest thermal performance coefficient was obtained with DR = 0.85 and PI = 7%.

Summary: In this study, the Taguchi approach and grey relation analysis were used to optimize the thermal and hydraulic characteristics of a circular tube using ternary hybrid nanofluids. The results showed that the Nusselt number was highest when the mass ratios of the nanoparticles were highest, while the friction factor was primarily influenced by the lowest mass ratios. The analysis also revealed that GnP nanoparticles had the highest contribution to the Nusselt number and friction factor, followed by MWCNT and Fe3O4. The optimum configuration was found to be a Reynolds number of 30,000, mass% of 0.4 GnP, 0.3 MWCNT, and 0.2FE3O4.

Summary: The present study experimentally investigates the effect of twisted tape inserts on the thermal performance of an eccentric inlet and outlet heat pipe evacuated-tube solar thermal collector (HP-ESTC). The results show that the addition of twisted tape inserts enhances heat transfer performance by eliminating stagnation flow, reducing flow skewness, and generating rotating flow. A comprehensive performance analysis considering both heat transfer and pressure drop characteristics confirms that using twisted tape inserts can improve overall performance by approximately 7.7%. To assess its applicability for commercial HP-ESTCs, an HP-ESTC containing twisted tape inserts was manufactured and tested outdoors.

A large pilot plant was also used to predict the pressure drop in the stripper column of Lavan oil manufacture. The experiments considered different outlet weir heights and hole areas. The results indicate that this type of centrifugal tray can be used in retrofit and revamping projects.

Summary: This paper presents a multi-objective experimental study on enhancing the thermal performance of a helically coiled pipe. The study evaluates the hydrothermal behavior of single-phase and two-phase flow through the helically coiled tube, with and without a helical wire insert. The results show that the exergy efficiency is higher by 87% without a turbulator for single-phase flow. The simultaneous use of two-phase flow and turbulator is recommended when pressure drop increment is less important than heat transfer augmentation.

Summary: This study experimentally investigated the effects of finned turbulators with different angles in a circular pipe on heat transmission and friction. The results showed that increasing the angle of the turbulator can improve the Nusselt number and heat transfer improvement factor. The turbulator with a 30 degrees angle had the highest Nusselt number, while the turbulator with a 20 degrees angle had the highest heat transfer improvement at Re = 10043. Additionally, the heat transfer improvement factors of the 20 degrees and 30 degrees angle turbulators were 1.1 times and 1.07 times higher, respectively, compared to the 10 degrees angle turbulator.

Summary: This study experimentally investigated the heat transfer characteristics and dynamic flow boiling instabilities of ethanol in a rectangular microchannel. The results showed that the inhibition of bubble nucleation caused by large bubbles in the confined space led to a deterioration in heat transfer performance. Higher mass flux resulted in more effective bubble nucleation and better heat transfer. The triggering of flow boiling instability in the microchannel was strongly dependent on quasi-periodical flow phenomenon and multiphase alternation. The thermophysical properties of the working liquid significantly affected the fluctuation amplitude.

Summary: This study investigates the effects of tube diameter, coil diameter, Reynolds number, Dean number, and flow rate on heat transfer and pressure drop in a helically coiled tube during laminar single-phase flows. The results show that helically coiled tubes have higher heat transfer but also higher pressure drop compared to straight tubes. The heat transfer coefficient increases with increasing Reynolds number, Dean number, tube diameter, and flow rate, while it decreases with increasing coil diameter. On the other hand, the pressure drop increases with increasing Reynolds number, Dean number, and flow rate, but decreases with increasing tube and coil diameter.

Summary: The effects of mixing secondary, spiral, and swirl flows on heat transfer and pressure drop in internal corrugated tubes with varying Reynolds numbers were examined. The results showed that heat transfer enhancement can be attributed to the convective heat transfer transformation and the redevelopment of the boundary layer by pulsation. Different corrugated geometrical configurations were also investigated, and it was found that higher configurations led to increased heat transfer. Using different corrugated geometric configurations resulted in improved performance compared to smooth pipes.

Summary: Numerical simulation was used to analyze the behavior of a flow field, pressure drop and hydraulic thermal performance. The results showed that the insertion of twisted tape in the pipe increased the pressure difference and flow resistance, resulting in a higher temperature difference. The twisted tape created vortex motion and different radial velocities, altering the behavior of the fluid. The geometric parameters of the twisted tape had an influence on the results, but the temperature difference increased less compared to a smooth pipe.

Summary: The low thermal conductivity of phase change materials limits the heat transfer rate and application of latent heat storage systems. This numerical study examines the impact of two passive heat transfer enhancement techniques on the thermal performance of a latent heat storage system. The results show that the orientation and position of the heat transfer fluid tube have significant effects on the charging duration, while the discharging duration remains unchanged. The combined effect of orientation and eccentricity reduces the charging duration, but increases the discharging duration compared to the concentric domain.

Summary: This paper investigates the calculation method of thermal conductivity in NAPLs-contaminated soils. By establishing NAPLs-contaminated soil models and using the Lattice Boltzmann Method (LBM) for calculation, an optimized three-dimensional model with high computational accuracy and efficiency is obtained. The study also finds that saturation and Nz parameters have a significant impact on calculation time, while the thermal conductivity of the two-dimensional model is more sensitive to anisotropy. The influence of porosity and NAPLs content on thermal conductivity should be considered during in-situ thermal desorption.

Summary: This study investigated the impact of upstream slot leakage on the endwall film cooling characteristics of turbine blades. Pressure Sensitive Paint (PSP) technology was used to measure the film cooling characteristics, and numerical analysis was conducted to evaluate the aerodynamic performance. It was found that increasing the mass flow ratio of the upstream slot enhanced film cooling, decreased aerodynamic losses, and reduced the strength of passage vortex. However, reducing the distance between the slot and the blade leading edge only enhanced film cooling without affecting the leakage coverage area.

Summary: We have developed an advanced experimental setup to investigate flow and heat transfer in an annular channel. The setup allows heat transfer measurements and flow visualization using a temperature-controlled inner tube. Measurements can be conducted in both single-phase and two-phase flow regimes. The setup ensures a uniform velocity field in the annular channel using specially designed inlet and outlet headers. The inner copper tube is heated by water and contains turbulators for enhanced heat transfer and thermocouples for temperature measurement. A three-dimensional conjugate heat transfer CFD model has been developed and validated to accurately estimate heat losses in the setup. This study demonstrates the importance of numerical simulations in improving the interpretation of complex experimental results.
