“…[32] The experiments were performed in a range of Rayleigh numbers ranging from 3500 to 32000, and results presented as variations in local and average Nusselt numbers for various portion angles and Rayleigh numbers. Baby and Sobhan [33] conducted interferometric measurements to study the effects of surface irregularities in meso-channels on their heat transfer performance.…”

The application of digital interferometric techniques in the measurement of forced convection in compact channels is examined. Michelson Interferometry and Mach-Zehnder Interferometry have been compared and contrasted, in terms of the suitability for temperature measurements. A wedge-fringe setting parallel to the heated surface has been utilized as the basis of the fringe analysis, for effective measurement in small dimension channels. Michelson interferometry was found to provide a larger number of data points in the visualization field, thus proving to be a better method of measurement in compact passages. Heat transfer parameters, useful in heat sink design, were also calculated.
