MAJEED, Abid; JAVED, Tariq; MUSTAFA, Irfan  and  GHAFFARI, Abuzar. Heat transfer over a stretching cylinder due to variable prandtl number influenced by internal heat generation/absorption: a numerical study. Rev. mex. fis. [online]. 2016, vol.62, n.4, pp.317-324. ISSN 0035-001X.

An analysis is carried out to investigate the two dimensional flow of an electrically conducting Newtonian fluid over a permeable stretching cylinder. The main objective of this study is to analyze the thermo-physical properties on the axisymmetric flow with Prandtl variable in the presence of internal heat generation/absorption. Unlike typical studies, the temperature dependent physical properties are discussed in highly coupled velocity and temperature fields. The solution of the problem is computed numerically with Chebyshev Spectral Newton’s Iterative Scheme (CSNIS) and results are shown through graphs for various emerging parameters. Moreover the exchange of energy from the surface to the fluid is examined through variations in Nusselt number. To verify our results, comparisons are made with the published studies which provides authentication of our present results and numerical scheme.

Keywords : Fluid flow; thermo-physical properties; permeable cylinder; variable Prandtl; boundary layer flow.
