Heat transfer from interrupted plates
Abstract
Heat transfer coefficients were measured in single and multiple flat plates equipped with interior heating elements and immersed in low Re flows in a wind tunnel. The plates were located successively in the tunnel and spanned the width of the channel. Attention was initially given to blunt leading edges, which were gradually reshaped in order to study various flow separation conditions over the course of the trials. Each plate was heated to 6 C over room temperature. The average value of a heat transfer coefficient for a single plate was determined to depend on the plate length and thickness, and may be inhibited by the leading edge separation bubble in the case of a blunt leading edge. Higher Re enhances the value of the coefficient. Turbulence induced by the presence of the first plate was observed to enhance heat transfer from the second plate.
