A Numerical Study of an MHD Fluid Flow along a Moving Cylinder using Fuzzy Concept

Abstract

As the real life problems are biased by uncertainty, consideration of those in fuzzy environment may be a better option to find the solutions. Since, the fluid flow problems are also vague and imprecise, here, we try to solve a boundary value problem (BVP) of fluid mechanics using fuzzy concepts. We consider a moving cylinder over which fluid flows, the governing equations and the boundary conditions of which are fuzzified by Zadeh’s extension principle and then they are solved numerically using finite difference method (FDM) by developing suitable computer programming code in Python (an object oriented programming language). α-cut technique is used to find the effects of various involved uncertain parameters on the velocity, temperature and species concentration distribution which are shown graphically and discussed.
