Shear Stress Transport

In this study, instead of changing the structure of the pin-fin array, the work focused on the design of protrusion/dimple points on the leading and trailing edges. Numerical simulations using the SST (Shear Stress Transport) turbulence model were performed to investigate the effect of dimple/protrusion concavity on flow structure and heat transfer characteristics in a rotating channel with pin-fin array.

In this paper, Ansys CFX commercial software is used to simulate the ventilation process in a parking basement. In addition, a simulation problem of ventilation in the office room is also performed to verify the reliability. In Ansys CFX, the Shear-Stress Transport turbulence model is used to determine the temperature and velocity of the tunnel and calculate the level of physical comfort according to ADPI standard.
