Abstract The process of the liquid spray impact on the heated surface is studied experimentally using the IR-transparent sapphire plate method. The spatiotemporal distribution of the temperature field on the sapphire substrate surface during impacting spray is received. The obtained experimental data are an important step in a study of the local characteristics of heat transfer in the areas of the contact lines during liquid spray impact on the heated surface. Further, the local heat fluxes and heat transfer coefficients will be determined by solving the problem of thermal conductivity in the sapphire substrate.

Abstract The spatiotemporal distribution of the temperature inside a constantan foil during impacting spray is resolved experimentally in the present work. The received infrared image sequence will be used to find the local and average heat transfer coefficient of the foil. In the future, the results obtained will be used to calculate the heat flux in the region of the contact line of each drop.

Closed Chambers

An experimental and theoretical study recently investigated the transient processes that occur when hot liquid spray droplets are suddenly injected into air contained in a closed chamber [1]. The analysis gathered all important parameters governing droplet heat transfer in a single dimensionless group, denoted by K2. The work has been extended by redefining K2, and introducing a new dimensionless group KN2, and by using helium as the surrounding gas. The dimensionless group KN2 is, to a first approximation, independent of all parameters investigated in the present work, including the properties of the surrounding gas, and approximately equal to 0.12. The dimensionless group KN2 =0.12 should be used instead of the Nusselt number as the primary dimensionless group in analysing the heat transfer performance of spray injection nozzles in closed chambers.

Complicated Process

The evaporation rate of a liquid spray in a turbulent gas stream is of interest in connection with direct contact heat transfer and combustion equipment. Any fundamental approach to this problem has usually dealt with single drops evaporating in an “infinite” atmosphere. The evaporation of sprays from actual atomisers is obviously a more complicated process and few attempts have been made to find in how far single drop data may be applied, or to measure the evaporation from a whole spray.The main difficulties lie in devising a satisfactory method of measuring the evaporation rate. Selden and Spencer, injected the liquid into a bomb filled with hot gas under pressure and measured the decrease in pressure with time on a special indicator.
