Design parameters for fluid flow simulation through mesh wick structures for thermal compressor systems

This research explores the transportation of a working fluid within a mesh wick structure at velocity of 12m/s. The research examines the influence of key design parameters on fluid flow through the mesh wick structure. By investigating these parameters, insights can be gained into optimizing the design for efficient fluid transport. This study investigates the thermal and fluid dynamics within a cylindrical mesh wick housing composed of aluminum and copper mesh materials. The wick structure comprises an inlet and outlet part, with four porous materials assembled together. By discretizing governing equations of continuity, momentum, and energy over the flow domain using Finite Volume-based equations in Ansys, accurate simulation results were obtained. An extra fine fluid mesh was employed to simulate conjugate heat transfer phenomena effectively. Temperature distribution within the porous wick revealed varying profiles, highlighting localized temperature variations near the outlet nozzle. Pressure distribution showed a gradient influenced by swirling velocities within the vortex at the inlet. Boundary heat flux sensible analysis demonstrated its significant impact on heat distribution and thermal management processes. Velocity profiles showcased uniformity at the inlet and increased velocity at the outlet, indicating the influence of porous wick on fluid flow dynamics. Overall, this research enhances understanding of thermofluidic flow through porous wick materials, crucial for optimizing thermal management systems and energy conservation processes.
