Abstract
The expansion of a two-dimensional flow due to the resistance of a wire gauze was studied analytically by applying revised Taylor's method in which the resistance of a gauze was replaced by the momentum change of flow from sources distributed on the plane of the gauze. Measurements were also made on the expansion of flow in a two-dimensional smoke wind-tunnel, and a good agreement between the calculated and measured profiles of flow was found. Additionally, flow observation and velocity-distribution measurement were carried out for a model diffuser designed by the analytical method.
