Abstract

Consider a steady flow analysis with temperature dependent viscosity and variable thermal conductivity near a rotating sphere. Additionally, a temperature dependent viscosity and variable thermal conductivity has been assumed for the current analysis. Partial differential equation system is converted into a differential system for distinct regions near the boundary layer region. Power series is used to calculate the solution of the problem. Ordinary differential systems are obtained by using this mythology. The sensitivity parameter shows reducing impact as it is showed for rotating disk problem. Temperature dependent liquid viscosity is analyzed to decrease the base flow profile the range, but for gases opposite impact is noticed. Variable thermal conductivity increase the temperature profile. The comparative results is evaluated for a limited case and good agreement is shown with previously published work.

期刊介绍： International Communications in Heat and Mass Transfer serves as a world forum for the rapid dissemination of new ideas, new measurement techniques, preliminary findings of ongoing investigations, discussions, and criticisms in the field of heat and mass transfer. Two types of manuscript will be considered for publication: communications (short reports of new work or discussions of work which has already been published) and summaries (abstracts of reports, theses or manuscripts which are too long for publication in full). Together with its companion publication, International Journal of Heat and Mass Transfer, with which it shares the same Board of Editors, this journal is read by research workers and engineers throughout the world.
