“…As mentioned by Lacona and Taine (2001;Gebhart et al, 1988), the gas has been preheated by convection along horizontal edge of the plate and radiation from cavity walls; also boundary layer thickness does not change considerably in the range of 10-40 mm and approximately corresponds to the difference between theoretical and experimental values. Also the optically thick approximation is not completely valid at the leading edge of the plate, which makes the analytical results lower the experimental data.…”

“…A similar study by Sabareesh et al (2010) was carried out for a hot plate with isoflux and isothermal boundary conditions. In an experimental study the effects of gas-gas radiation on thermal fields in a gas flowing by free convection around a finite isothermal plate was investigated by Lacona and Taine (2001). Holographic interferometry and laser beam deflection techniques were used to show the radiation heat transfer effects on boundary layer for both absorbing (CO 2 ) and non-absorbing (N 2 ) mediums.…”

A similarity solution for laminar boundary layer in a buoyancy induced flow over an isothermal, vertical wall in the presence of radiation is developed. Radiation heat transfer is taken into account by application of the Rosseland approximation in the energy conservation equation. The family of similarity solutions to the governing equations is presented. The computed results show that thermal and momentum boundary layer thickness values are increased as a result of radiation heat transfer. Furthermore for higher values of the radiation parameter, the maximum velocity inside the boundary layer increases.

“…When large refraction effects are present, special reconstruction techniques are required, since both the path of the light and the refractive index fields are unknown. The reader is referred to interferometric measurements that have been made in the presence of strong refraction by Lacona and Taine [48] and Dietz and Balkowski [49]. Depending upon the specific situation, corrections for other sources of error should also be considered.…”

An introduction is given to the optical setup and principle of operation of classical and holographic interferometers that are used for convective he at transfer measurements. The equations for the evaluation of the temperature field are derived and methods of analysis are discussed for both two-dimensional and three-dimensional temperature fields. Emphasis is given to techniques for measuring local heat transfer rates. For two-dimensional fields, a method is presented for measuring the surface temperature gradient directly from a finite (wedge) fringe interferogram. This “direct gradient method” is shown to be most useful for the measurement of low convective heat transfer rates. For three-dimensional fields, the equations for calculating the beam-averaged local heat flux are presented. The measurement of the fluid temperature averaged along the light beam is shown to be approximate. However, an analysis is presented showing that for most cases the error associated with temperature variations in the light beam direction is small. Digital image analysis of interferograms to obtain fringe spacings is also discussed briefly.

“…Methods to minimize refraction error and correction equations have been proposed [2][3][4][5]. More recently, the analysis of strongly refracting fields has been studied ( [6,7]). The error caused by end effects (in the absence of optical windows) has also been analyzed analytically by Goldstein [2] and Mehta and Black [4].…”
