“…Tamkhade et al, 2023 [5], the evaluation of performance to a double-pipe heat exchanger with an inner tube made of stainless steel, and an outer tube made of galvanized iron was investigated numerically by using CFD analysis. With hot water (80°C) and 2 LPM in the inner tube and cold water (30°C) and 10 Lpm in the outer tube as the working fluids, nickel metal foam with pore densities (10 to 50PPI) and 0.9 porosity is used.…”

The present numerical study aims to explore the effect of metal foam’s volume on the performance of a double-pipe heat exchanger in comparison with a smooth pipe (HXS). It used water as operating fluid at flow rate 2lpm, the outer stainless steel pipe has outer diameter (Do=60mm) and length (L=609.6mm), and inner copper pipe with outer diameter (do=20mm). The numerical simulation was conducted by ANSYS FLUENT 2020 R2 software and open-cell copper foam (CF) with porosity (0.9) was used. The cases considered in the analysis include a heat exchanger with a complete fill of copper foam (HXF), and a partial fill heat exchanger. The latter was made by inserting a complete rings of copper foam baffles (CFB) to decrease volume of a CF. Then, the baffles volumes was increased by increasing the thickness and their number. Three parameters were varied and their influence on performance evaluate criteria (PEC) were investigated. They are pore density (PPI), thickness of baffles (tc), and number of baffles (nob). Results showed that, heat transfer rate (Qave) and the pressure drop (∆p) increased with increase pore density, and well distribution of a CFB increase thermal performance while the pressure drop did not change with use same volume of CF.

Almost all thermal systems utilize some type of heat exchanger. In a lot of cases, evaporators are important for systems like organic Rankine cycle systems. Evaporators give a share in a large portion of the capital cost, and their cost is significantly attached to their size or transfer area. Open-cell metal foams with high porosity are taken into consideration to enhance thermal performance without increase the size of heat exchangers. Numerous researchers have tried to find a representation of the temperature distribution closer to reality due to the different properties between the liquid and solid phases. Evaporation heat transfer in an annular pipe of double pipe heat exchanger (DPHEX) filled with cooper foam is investigated numerically with utilizing the local thermal non-equilibrium (LTNE) model. Warm water with constant inlet conditions flows in the inner pipe while R143a is used as cooling fluid in the annular pipe. The effects of pores per inch (PPI), mass flux of R134a and copper foam porosity on solid and fluid temperatures, liquid saturation and heat transfer coefficient are analysed and illustrated. Forchheimer-extended Darcy flow model is utilized with the adopting of the twophase mixture model (TPMM). The governing equations in two-dimensional steady state regime were written in LTNE model. These equations were discretized using the finite volume method and a MATLAB program was built to solve these equations with its initial and boundary conditions. The obtained data illustrates that LTNE effect in metal foam is important for lower porosity, lower pore density and higher mass flux. The ratio of liquid will arrive its lowest value at the outlet, and it decreases with PPI increase and it increases with porosity and mass flux increase. The mean heat transfercoefficient approximately doubled when PPI increased from 10 to 50 and it increased by 70% when porosity decreased from 0.95 to 0.85.
