Краткое описание

An experimental investigation was carried out to study the heat transfer and turbulent flow over a flat plate in a wind tunnel. The turbulence was generated by a turbulence generator with a finite height mounted perpendicular to and on the leading edge of the flat plate. Instantaneous velocity measurements were performed with a 1D hot-wire anemometer to investigate the behavior of the flow a short distance downstream of the perforated plate. Temperature distribution and heat flux along the centerline of the plate with and without the perforated plate at the leading edge were measured. The results showed that significant wind blockage limited the turbulence generator (TG) to be effective in lowering the flat plate temperature to within a short distance downstream. Detailed flow measurements revealed that the orifice perforated plate that generated flow turbulence is superior in augmenting the Nusselt number. To realize its full potential, however, the drastic blockage caused by the current turbulence generator design needs to be mitigated.
