Unstructured finite volume computational thermo-fluid dynamics method for multi-disciplinary analysis and design optimization

摘要

This paper describes a finite volume computational thermo-fluid dynamics method to solve for Navier-Stokes equations in conjunction with the energy equation and the thermodynamic equation of state in an unstructured coordinate system. ^The system of equations has been solved by a simultaneous Newton-Raphson method and compared with several benchmark solutions. ^Excellent agreement has been obtained in each case, and the method has been found to be significantly faster than the SIMPLE algorithm and therefore has the potential for implementation in multidisciplinary analysis and design optimization in fluid and thermal systems. ^The paper also describes an algorithm of design optimization based on the Newton-Raphson method. ^(Author)
