Air side heat transfer and flow characteristics simulation of multi-unit parallel flow evaporators

Simulates and analyses the air side heat transfer and flow characteristics of louver fins of multi-unit parallel flow evaporators, and obtains the pressure field and temperature field at the different louver angles. Compares the air side heat transfer coefficient and pressure drop calculated by numerical simulation with those calculated by the experimental correlation formula in relevant literatures, and verifies the feasibility of the model and method adopted in numerical simulation. Analyses the influence of louver spacing on the air side heat transfer and resistance characteristics, and finds that there exists an optimum louver spacing to maximize the air side heat transfer coefficient.
