Keywords:

microconvection; thermal properties; the thermal flux


Abstracts:

An experimental study of the process of microconvection in a cell formed by the cylindrical shape of the elements and the different thermal properties was performed. The working fluids were following: water, isopropyl alcohol and methylene chloride. We used a method of holographic interferometry, which allows to fix the change of temperature fields in the study area. Results on the visualization of temperature fields and the development of convective flows in unsteady heating in the lower part of the wall of the cell. The conditions of microconvection depending on the thermophysical properties of the liquid and the supplied quantity of heat flow.
