Abstract
  In this article, the idea of building a supersonic wind tunnel has been provided that uses a high-pressure steam flow of a combined cycle power plant. This has been investigated by CFD method. Using the plant's output steam as a high-pressure source can be used in the ejector to create supersonic airflow ...  Read More

Airfoil Shape Optimization with Adaptive Mutation Genetic Algorithm

A. R. Jahangirian; M. Ebrahimi

Volume 11, Issue 1 , June 2017

Abstract
  An efficient method for scattering Genetic Algorithm (GA) individuals in the design space is proposed to accelerate airfoil shape optimization. The method used here is based on the variation of the mutation rate for each gene of the chromosomes by taking feedback from the current population. An adaptive ...  Read More
