Laminar Forced Convection to Mixtures of Inert Gases in Parallel Plate Ducts.
Abstract
Heat transfer and wall friction parameters were obtained numerically to demonstrate the effects of mixture composition and gas property variation for heating or cooling in regenerative heat exchangers; the situation is modelled by laminar flow through short ducts with constant wall heat flux. For design predictions accounting for the effects of property variation, the property ratio method is better than the film temperature method for heat transfer while the latter method is preferable for apparent wall friction--providing that the present definitions of the non-dimensional parameters be employed.
