Heat transfer analysis in convective flow of Jeffrey nanofluid by vertical stretchable cylinder

摘要

This paper studies the magnetohydrodynamic (MHD) flow of unsteady Jeffrey nanofluid due to vertical stretchable cylinder. Joule heating and thermal radiation outcomes are additionally addressed. The Buongiorno model is utilized to describe the characteristics of nanofluid. The mathematical form of the problem consists of momentum, continuity, concentration, and energy equations. Suitable transformations are employed to obtain the dimensionless form. Numerical solutions for velocity, energy and concentration equations are obtained by the finite difference method (FDM). Impacts of various parameters (i.e. Prandtl number, Eckert number, Hartmann number, Grashof number, Deborah numbers, Brownian parameter, stretching parameter and Schmidt number,) on velocity, concentration, temperature, Nusselt and Sherwood number numbers are scrutinized graphically. Results show that velocity decays for higher Grashof number and stretching parameter. Temperature and concentration decreased for higher Brownian parameter, Prandtl and Schmidt numbers.
