An experimental study has been done to elucidate effects of mass flux G, degree of subcooling ΔT_<sub>, initial solid temperature T_<b0> and thermal properties of test liquid and hot block on wetting temperature during spray cooling of a hot block. The experiments were done up to maximum mass flux of 12kg/(m^2s) and maximum subcooling of 80K with copper, brass and carbon steel blocks, water and ethanol sprays. Surface temperature and surface heat flux on transient transition boiling region were evaluated with an axisymmetric 2D inverse heat conduction analysis. The wetting temperature is defined as the surface temperature at the minimum heat flux point. It is found that the characteristic of the wetting temperature is categorized into two regions by GΔT_<sub>.
