Abstract
A regenerator wire mesh obtained by knitting, lengthwise and crosswise, whose wires' cross sectional shape are streamline to the flow, is considered to become smaller flow resistance than usual wire mesh of circular cross-sectional shape. Although, Nusselt number may be decrease a little bit than usual mesh, wire mesh having streamline cross-sectional shape is probably superior to that having circular shape cross section because the effect of decrease of flow resistance is larger than that of Nusselt number. In order to confirm this idea, comparison between parallel thin flat plates' flow and cross flow over banks of circular cylinders is carried out. Also simple numerical calculation was carried out.
