内容記述
Turbulent free convection heat transfer from vertical parallel plates (5m length), which were a plate with uniform heat generation and a thermally insulated plate, was experimentally studied for air. Measurements were made for 9 pairs of the two hydrodynamic conditions, which were an interplate spacing B (=50,95 and 195mm) and a leading edge height H (=10,90,170 and 465mm) of the vertical plates from a floor, in the range of the heat generation rate between 52 and 208W/m^2. Experimental results demonstrated that heat transfer coefficients (based on inlet fluid temperature) on the higher vertical location from the leading edge than 2m were almost independent of H excepting H of 10mm and were reduced with decreasing B.
