Optimizing Temperature Gradient in the Thermal Transpiration Pump

This study aimed to investigate methods for achieving a greater temperature gradientGradient between the hot and cold chambers in a thermal transpiration pump. Three cases were examined to assess the ability of supplying consistent heat supply: the basic hot chamber, the insulated hot chamber, and the insulated hot chamber with wire mesh inside the chamber. The temperature differences were analyzed in each case, both with and without cooling system. The cooling system was used to determine its impactImpact on the temperature of the cold chamber and its ability to lower the temperature of the water. The results showed that the cooling system was effective in improving the temperature of the cold chamber. It allowed the water to cool to a lower temperature. The hot chambers with additional rockwool and wire mesh achieved higher temperatures compared to other hot chamber conditions. Overall, the study suggests that incorporating rockwool around the hot chamber and mesh screen inside, along with implementing a cooling system, can lead to a greater temperature gradientGradient between the hot and cold chambers for better operation of thermal transpiration pump system.
