Application of the laser beam deflection to the study of temperature fields in Rayleigh–Benard convection

Application of the laser beam deflection to the study of temperature fields in Rayleigh–Benard... An optical integral and unobtrusive method is developed to determine the temperature gradient field by measurement of laser beam deflection induced by optical index changes. The technique is inexpensive and easy to perform. It allows the study of the temperature gradient at a large number of points simultaneously (over 400/cm2). This technique is particularly adapted to two-dimensional convection flow in both unsteady and steady conditions. For illustration purposes, such a technique is applied to the roll pattern of Rayleigh–Bénard convection. The agreement between theory and experiments is fair. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Experiments in Fluids Springer Journals
