Owing to their wide ranging applications in geophysical, oil wells, food processing and allied engineering settings, there has been a renewed interest in studying the flow and convective heat transport in visco-plastic fluids. Therefore our objective is to understand the flow and heat transfer characteristics of visco-plastic fluids.
One of the main distinguishing features of the visco-plastic fluids is the simultaneous presence of fluid-like (yielded) and solid-like (unyielded) regions in the flow domain depending upon the local stress levels vis-Ã -vis the yield-stress of the fluid. This introduces new complications while studying heat transfer in such systems. Thus, for instance, condu...
