Book excerpt: The effects of coolant-to-mainstream density ratio (D.R.) and mass flux (blowing) ratio (Mb) on flat plate heat transfer were investigated in a shock tube. The round-nosed plate has a single row of holes inclined 35 deg downstream with two-diameter lateral spacing and hole length of three diameters. Mixing helium with air in the shock tube produced a D.R. range of 1.2 to 2.1. The parameters studied approach those of film-cooled turbine components. For an Mb range of 0.4 to 3 and 10% mainstream turbulence, heat flux was measured with thin-film heat flux gauges located 4 to 30 hole diameters downstream of the cooling holes using an electrical analog. Various flow conditions were produced over the flat plate. The 'steady' portion of turbulent flow heat transfer data compared within 20% of the theoretical flat plate solution. Ratios of heat flux with cooling to heat flux without cooling versus M. and D.R. were determined. Analysis of the results showed film cooling heat transfer is correlated by coolant-to-mainstream velocity ratio. Effectiveness of cooling was reduced by the high mainstream turbulence.

Available in PDF, EPUB and Kindle. Book excerpt: The heat transfer mechanisms taking place in the flow induced behind a shock wave travelling across a flat plate were investigated for flat plates with sharp and rounded leading edges. The boundary layer behind the shock is described by a transient boundary layer followed by a steady state boundary layer as the effects of the leading edge are transmitted downstream. The use of a multichannel high speed transient data recorder allowed thin film heat transfer gages at up to eight axial locations along the length of the flat plate to be simultaneously sampled. Heat transfer rate histories for each axial location were time correlated to the same flow conditions. The results indicate the existence of a threshold free system velocity (relative to the plate) above which are confined to some narrow interval. For Mach numbers below 1.22, the sharp leading edge flat plate experienced heat transfer rates in excess of theory, but the rounded leading edge flat plate data showed a consistent correlation between heat transfer magnitude and axial location on the plate; with limited data, the rounded plate showed no such correlation.

Book excerpt: The heat transfer mechanisms taking place in the flow induced behind an incident shock wave traveling across a flat plate were investigated. The boundary layer behind the shock is described by a transient boundary layer followed by a steady state boundary layer as the effects of the leading edge are transmitted down stream. The transition from laminar to turbulent can take place in either boundary layer. Limited data exists on the transition region. The use of a multichannel high speed transient data recorder allowed thin film heat transfer gauges six axial locations down the length of a sharp edged flat plate to be simultaneously sampled. From this the heat transfer rate history for each location was time correlated to the same flow conditions. The results indicate that the transition from laminar to turbulent flow is occurring from the unsteady region of the flow. The initiation of transition to turbulent flow occurs at successive gauge locations at the same time relative to the incident shock passing the gauge position. Limited evidence is presented which indicates that the leading edge may retard the initiation of transition at gauge locations close to the leading edge may retard the initiation of transition at gauge locations close to the leading edge if the steady Reynolds number for the flow behind the incident shock is in the laminar regime.
