要約

The convective heat transfer rate from an isothermal vertical flat plate adjacent to a venetian blind has been studied using finite element code. This investigation was undertaken to determine the effects of blade-to-plate spacing, d, and blade angle, θ, on the flow pattern and convective heat transfer coefficients. Results are presented for values of d= 15, 20, 25, 30, and 40 mm, and at each of these .spacings, blade angle was varied, i.e., θ=0 °, 45°, -45°, 80°.As a verification of the modelling, a common base-case, i.e., the laminar natural convection on an isothermal, vertical flat plate was studied. Comparisons with experimental results were also made for both local heat flux and flow distribution for d = 15 mm.
In the present study, a two-dimensional finite element numerical model was developed to investigate the effects of a venetian blind on the free convection heat transfer adjacent to an isothermal vertical surface.
