Abstract

In the study of thermal convection in the opaque magnetic fluids convective rolls can be visualized using the thin textolite plate and infrared camera. The plate is one of the boundaries of the convective cavity - vertical layer. The possibility of quantitative measurements of temperature fields of the liquid surface is evaluated by this method. Temperature fields in thin textolite plate, bounding the fluid layer, non-uniform temperature, have been calculated. Laboratory modeling of periodic convective structures to study the temperature distribution along the plate, obtained with an infrared thermal imager, has been performed. According to the results of calculations and experiments systematic measurement errors of spatial harmonics of the thermal field, generated by a convective flow, have been evaluated.Received 11.11.2015; accepted 18.01.2016
