Chemiluminescence (CL) occurs during reactions of several of the components of the CH2 (COOH)2-KBrO3-MnSO4-H2SO4 self-sustained system. In contrast to the kinetics determined using potentiometry and spectrophotometry, the CL intensity kinetic curve during the oxidation of manganese (II) ions by acidic bromate has an extremum. Experimental dependences of the maximum CL intensity value on the initial reagent concentrations have been determined and compared with the results of the numerical simulation based on the commonly accepted Noyes-Field-Thompson mechanism.

Characteristics of heat transfer and hydrodynamics of boiling of liquid nitrogen on the surfaces with different types of non-uniformities at the presence of external electric fields are experimentally investigated. It is shown that the formation of field traps is a major mechanism of heat transfer enhancement. And this effect result in noticeable change of two-phase hydrodynamics in vicinity of heated surface.
