تعیین پارامترهای طراحی هندسی مبدلهای حرارتی بالش

In this study, a determination method for the hydraulic diameter, cross-sectional area and heat transfer area is proposed for pillow-plate geometries. The method is based on forming simulations, which accurately reproduce the inherently three-dimensional wavy pillow-plate channels by imitating the real manufacturing process of pillow plates. The simulation results are then used to develop simple expressions for the geometric design parameters.
