主 题:spray cooling potassium chloride ethylene glycol heat transfer coefficient
摘 要:As an efficient cooling method for high heat flux field,spray cooling has a great application potential on aircraft directed energy weapon *** on previous research results,an experimental system of open-loop spray cooling was established,and the potassium chloride aqueous solutions and ethylene glycol aqueous solutions with different mass fractions were applied to investigate the influence of different additives on spray cooling system ***,theoretical analysis was conducted according to the droplet breakage principle and the characteristic parameters of fluid *** results indicate that heat transfer can be enhanced by adding potassium chloride up to a certain concentration and then decrease with higher *** transfer is deteriorated with the increase of ethylene glycol *** of the two additives can reduce the freezing point of the system,and ethylene glycol is preferred to improve the application range of the system in consideration of the corrosion of salt solution.
