Abstract
The current research focuses on numerical simulations of recovering low-grade airborne heat to co-save a portion of the energy used by household ventilation. The investigation of three-dimensional steady-state turbulent flow and heat transfer utilizing the CFD approach and the finite volume method with ANSYS software to solve the Naiver Stock and energy equations. The turbulent flow model is governed by the k-ε turbulence model with the SIMPLE-discretization algorithm. To enhance the recovering system thermal performance, two baffles are inserted into both inlet hot and cold channels with changing their inclination (45, 90, and 135°) respectively. The Thermo aerodynamic performance assessments are included velocity, temperature, and effectiveness distribution along with airflow from the leading edge to the end of the core, through the two baffles. The results reveal simply that the flow is characterized by significant deformations. When fixed inclination baffles (45°) are added inside the channel at a constant Reynolds number, the efficacy increases by 35%.
