Enhancement of Heat Transfer and Air Flow Rates in a Pipe with Application of a Magnetic Field
Краткое описание
The enhancement of flow and heat transfer rates of air flow in a pipe was studied when a gradient magnetic field was applied at a point of step heating in the wall. Numerical computations were successfully carried out for initial Reynolds number, Re0 = 50, 100, and 200; for pipe lengths L = 10, 20, and 30; and values of x = 105 - 2 ґ 106, which represents the strength of the magnetic field and the temperature difference between that of a pipe wall and that of inlet air. Application of a gradient magnetic field induced strong radial velocity components that decreased the thickness of the velocity and thermal boundary layers and increased both volume flow rate and the local Nusselt number to more than twice the value of the Graetz solution for the present parameters of computation.
