Thermal boundary layer of a micropolar fluid on a circular cylinder
Abstract
Steady thermal boundarylayer flow past a circular cylinder whose axis is placed normal to an oncoming free stream of an incompressible micropolar fluid has been studied. The solution of the energy equation inside the boundarylayer is obtained as a power series of the distance measured along the surface from the front stagnation point on the cylinder. The surface of the circular cylinder is maintained at a constant temperature and the temperature outside the boundary layer is also kept constant. The dimensionless temperature distribution and the heattransfer coefficient have been presented graphically for various values of the material parameters. A comparison has been made with the corresponding results for Newtonian fluids. The temperature inside the boundary layer is more, and the heattransfer coefficient is less, for micropolar fluids as compared with that for Newtonian fluids.
