Summary: This study experimentally investigates and optimizes the performance of a novel spray flash desalination system integrated with concentrated solar power. The effects of flow rate, feed water temperature, salinity, and vacuum pressure on condenser exit temperature, boiler exit temperature, and distillate production are examined. Mathematical models are developed for each response, and optimization is conducted using Design Expert software and response surface methodology. The results indicate that feed water temperature and vacuum pressure have a positive impact on condenser and boiler exit temperatures, while salinity and flow rate have a negative impact. However, flow rate, feed water temperature, and vacuum pressure positively affect distillate production. The optimal factor settings are 0.4 LPM flow rate, 50 degrees C feed temperature, 15,000 PPM salinity, and 0.5 bar vacuum pressure, resulting in an optimal condenser exit temperature of 55 degrees C, boiler exit temperature of 58.8 degrees C, and distillate production of 7010 mLPH. Energy and exergy analyses are conducted, with mean efficiencies of 55.6% and 2.2%, respectively.

Summary: This study investigates the effects of cutting electrical steel laminations using abrasive water jet (AWJ) and wire electrical discharge machining (WEDM) techniques on the efficiency and magnetic losses of a 5.5 kW induction motor. The results show that AWJ cutting leads to burr formation while WEDM cutting results in recast layer formation. Both cutting methods result in decreased efficiency and increased magnetic losses with increasing frequency and motor loading rate. The optimum results, determined using Response Surface Methodology (RSM), are achieved at a frequency of 50 Hz and a motor loading rate of 100% in both cutting methods. Analysis of variance (ANOVA) reveals the statistical effects of frequency and motor loading rate on efficiency and magnetic losses.

Summary: This study explored the performance of bamboo particle boards (BPBs) made from unsaturated polyester resin (UPR) with toluene diisocyanate (TDI) as the coupling agent. Results showed that covalent bonds were formed among TDI, bamboo particles, and UPR, significantly enhancing the mechanical strength and improving thermal stability. The treated BPBs exhibited significant improvements in internal bonding strength, modulus of elasticity, and modulus of rupture, and had lower thickness swelling rate. Therefore, using UPR as the adhesive and TDI as the coupling agent in BPBs offers better usability, higher efficiency, and excellent mechanical strength.

Summary: Due to its flexible motion characteristics, helical milling is able to achieve high surface quality and cutting stability. In the medium density fiberboard (MDF) helical up-milling process, the effects of input parameters on specific cutting energy (SCE) were investigated. The results showed that the helical angle and depth of milling had extremely significant effects on SCE, while the rotation speed of the main shaft had a non-significant impact. A quadratic model was established to accurately predict SCE. The optimized parameters for helical angle, rotation speed, and depth of milling were determined. Although there was a slight increase in surface roughness under the optimized milling parameters, the optimization was feasible at the initial rough machining stage. These findings are important for guiding the selection of processing parameters to reduce SCE.

Summary: The CO2 laser is used as an environmentally friendly thermal treatment for wood materials due to its advantages of short treatment period and no wastewater and oil produced. However, it also affects the surface roughness of the treated wood, which in turn affects the wooden product properties. This study analyzed the influence of laser parameters on surface roughness and found that laser power increased the surface roughness of poplar wood, while feed speed and path spacing decreased the surface roughness. It is important to scientifically predict and guide the selection of reasonable modification process parameters for the modified wood surface.

Summary: Helical milling of Scots pine was studied to evaluate machinability based on surface roughness and milling power consumption. The results showed that surface roughness decreased with an increase in helical angle and rotation speed, while increased with an increase in milling depth. However, milling power consumption increased with an increase in helical angle and milling depth, but showed a slight downward trend with an increase in rotation speed. The optimized combination of helical angle, rotation speed, and milling depth were determined to improve surface quality and save power consumption.
