Studies have been performed in spray cooling with phase change using water as the coolant. A gas atomizing nozzle was used with both air and steam as the driving gases. The effect of gas atomizing pressure and liquid flow rate on the heat transfer, specifically, the critical heat flux, is studied. Spray droplet size and velocity, liquid film thickness, and flatness were measured using phase Doppler, Fresnel diffraction, and holographic techniques, respectively. The effect of spray characteristics on film thickness and heat transfer is discussed. The studies indicate that for a given secondary gas flow rate there exists an optimal liquid flow rate at which a maximum CHF is obtained. The spray cooling technique provides a wide heat flux operating range for small changes in system temperatures. |
