A perturbation analysis of the steady integral flow and heat transport of gases in rod bundles, Part 1: Asymptotic analysis of plane turbulent CouettePoiseuille flows, Part 2
Abstract
The basic field equations for flow and heat transport are made dimensionless, or scaled, according to the characteristic conditions of current gascooled rod bundle design. Through the use of an integral theorem over subdivision of the flow field, called subchannels, subchannel equations were obtained from the scaled field equations. The scaled subchannel equations include two small parameters which uncouple the energy equation from the momentum and continuity equations and which show that the pressures in all subchannels are equal except in the vicinity of singularities caused by rod spacing structures (spacers). Solutions to the scaled subchannel equations were derived in terms of perturbation series in the two small parameters.
