The high flow-rate centrifugal fan needs a three-dimensional impeller to achieve a high efficiency. In this paper, the design procedure of a high-efficiency thr
The volumetric flow rate of smoke generated from the fire in large space often reaches to hundreds of thousands CMH because of extended floor height and as it’
The aim of this study is to present an alternative approach for solving the multi-objective posynomial geometric programming problems. The proposed approach min
