A technique to measure the instantaneous two-dimensional temperature and velocity distributions of water was established using laser-induced fluorescence (LIF) and particle image velocimetry (PIV). Many of considerations were calibrated to eliminate the fluctuation of the measurement of temperatures. Horizontal thermal jet was measured by this system to evaluate the total accuracy of the measurement system. A random error of the measurement was ±1.7℃. Measurement of an unsteady penetrative convection showed typical turbulence large structures.
