Summary: This paper investigates the effect of a perforated twisted tape insert (PTTI)-based heat exchanger (HX) using nanofluid as working fluid. The study explores the impact of nanofluid mass flow rates, perforated pitches, and perforated diameters on fluid outlet temperature, Nusselt ratio, friction ratio, pressure drop, overall thermal performance, CO2 discharge, and heat exchanger operating cost (HXOC). The research also focuses on design optimization using the Taguchi-Grey method. The results show that the PTTI in HX achieves overall heat transfer enhancement, but at a higher pressure penalty compared to plain tubes.

Summary: Scraped surface heat exchanger (SSHE) is widely used in various industries to improve energy efficiency and facilitate energy transfer between fluids. This study investigates the steady isothermal flow of a rheological aqueous ionic solution in a narrow gap SSHE, establishing a mathematical model using lubrication approximation theory and extracting analytical solutions. Exact analytical expressions are obtained for velocities, volume fluxes, pressure gradients, pressure at the edges of the blades, and stream functions at different stations of the SSHE. Various plots reveal the impact of significant flow parameters on the aforementioned variables. It is observed that increasing the ratio of relaxation to retardation time parameter and Helmholtz Smoluchowski velocity improves the velocity profile in the main flow domain, while the electro-osmotic parameter impedes the flow.

Summary: In this study, the Reynolds Averaged Navier-Stokes (RANS) simulation was used to predict turbulent flow in a standard stirred tank with a liquid-liquid two-phase system. The comparison between the standard k-epsilon model and the Renormalization Group (RNG) k-epsilon model showed that the corrections made to the constants of the transport equations reflected the time-averaged strain rate of the main flow. Multi-dimensional investigation revealed the flaws of the RNG k-epsilon model in predicting the liquid-liquid two-phase mixing process, providing guidance for the selection of turbulence models.

Summary: In this study, a magnetic field coupling fractional step lattice Boltzmann (FSLB) model is proposed for simulating complex interfacial behaviors in magnetic multiphase flows. The model accurately recovers the macroscopic governing equations and achieves second-order accuracy through the use of equilibrium and non-equilibrium terms obtained from Chapman-Enskog (C-E) expansion analysis. The method predicts intermediate variables by updating the moments of equilibrium distribution functions first, and then corrects the physical variables by updating the moments of non-equilibrium distribution functions.

Summary: In this paper, a central moment discrete unified gas-kinetic scheme (DUGKS) is proposed for multiphase flows with large density ratio and high Reynolds number. Two sets of kinetic equations are used to approximate the incompressible Navier-Stokes equations and a conservative phase field equation for interface-capturing. The DUGKS framework defines velocity as the first moment of the distribution function for the hydrodynamic equations and carefully defines the zeroth moments to recover an artificial pressure evolution equation. Benchmark tests are conducted to demonstrate the capabilities of the proposed scheme, and the numerical results are in good agreement with theoretical and experimental data.

Summary: This study utilizes direct numerical simulations to investigate the changes in mean particle drag caused by turbulent environments and the responsible mechanisms. The study confirms that turbulent environments significantly enhance the particle drag, and the enhancement cannot be explained solely by the nonlinear dependency of drag force on the incoming flow velocity. Two mechanisms of particle-turbulence interactions are identified as responsible for the drag enhancements. General models accounting for turbulence anisotropy are proposed for quantitative drag enhancement predictions. It is also found that the overall particle drag increases with decreasing particle-particle relative gap distance, while the relative enhancement due to turbulence decreases with the particle-particle relative gap distance.

Summary: The present study improves the understanding of the sedimentation behavior of two flat disks in a viscous fluid through direct numerical simulation and physical experiments. The results show that the shape of the disks, characterized by dimensionless moment of inertia I* and Reynolds number Re, significantly influences the sedimentation processes. The behavior of the disks transitions from steady falling to periodic swinging as Re increases for flatter disks with smaller I*. Disks with larger I* tend to fall in a drafting-kissing-tumbling mode at low Re and remain separated at high Re. A phase diagram is created based on I* and Re to classify the falling behavior into ten distinctive patterns. The planar or three-dimensional motion of the disks is primarily determined by Re, with turbulent disturbance flows contributing to chaotic three-dimensional rotation. The chance of contact between the two disks is increased when I* and Re are reduced.

Summary: Mixing performance for a consecutive competing reaction system in a swirling vortex flow reactor (SVFR) was investigated. The Direct Quadrature Method of Moments combined with the interaction by exchange with the mean (DQMOM-IEM) method was used to model such reacting flows. Macromixing was rapidly achieved due to the swirling feature of the reactor, while micromixing was sensitive to turbulence. Ultrasound irradiation was found to significantly improve mixing uniformity and reduce by-products. The SVFR, especially intensified by ultrasound irradiation, was suggested to provide efficient mixing performance for fine-particle synthesis.

Summary: The head-on collision between two droplets near the critical point was studied using the Boltzmann-BGK equation. Different degrees of precision in the Gauss-Hermite quadratures were employed to solve the kinetic equation, enabling comparison between solutions truncated at the Navier-Stokes order and non-continuum solutions. Prominent variations of vertical velocity, viscous stress components, and droplet morphology were observed during the formation of a liquid bridge, highlighting the importance of rarefaction effects and the limitations of the Navier-Stokes equation. The study identified rarefaction effects that alter streamlines near the droplet surface, suppress high-magnitude vorticity concentration in the interdroplet region, and promote vorticity diffusion around the outer droplet surface.

Summary: In our recent paper, we find that hidden errors can occur in the bounce back scheme at the boundary nodes, which may not be consistent with the Chapman-Enskog approximation of the lattice Boltzmann equation for the interior nodes. We investigate the effects of these hidden errors on the lattice Boltzmann simulation of turbulent channel flow with a multiple-relaxation-time collision model. The results reveal important differences in the expression of hidden errors between two bounce back schemes.

Summary: In the past decade, there has been a growing interest in studying energy systems for the combined management of power vectors. Most of the published works focus on finding the optimal design and operations of Multi Energy Systems (MES). However, for newcomers to this field, understanding how to achieve the desired optimization details while controlling computational expenses can be challenging and time-consuming. This paper presents a novel approach to analyzing the existing literature on MES, with the aim of guiding practical development of MES optimization. Through the discussion of six case studies, the authors provide a mathematical formulation as a reference for building the model and emphasize the impact of different aspects on the problem nature and solver selection. In addition, the paper also discusses the different approaches used in the literature for incorporating thermal networks and storage in the optimization of multi-energy systems.

Experimental validation results show that thermal radiation accounts for a significant proportion of the total heat exchange in the reactor and a large amount of radiant energy exists in the important spectral range of supercritical water. Enhancing radiative heat transfer can effectively increase the temperature of the reaction medium and the gasification rate.
