Numerical Simulation of Forced Convection Heat Transfer from an Ellipsoid of Revolution, Using a Fourier Spectral Method
RÉSUMÉ
Forced convection heat transfer from an ellipsoid of revolution is analyzed numerically. By assuming fluid properties to be constant, and introducing boundary-fitted conformal mapping coordinate system (in the plane), the energy equation can be decpomposed into Fourier components in one space coordinate using a form of Fourier series for temperature and a function relating to an axially symmetric stream function in the same space coordinate; the decomposed equation can be discretized in another spatial coordinate, using substantially doubly-exponential grid spacing, to get relatively accurate thermal field and a mean Nusselt number even at a relatively high Reynolds number flow past a body of revolution (from a thin prolate spheroid to an oblate spheroid.)
