On Maximum Evaporation Rates of Liquid Droplets in Rocket Motors

Penner, S. S.


Upper limits have been estimated for the rate of evaporation of small liquid droplets in representative rocket combustion chambers. The droplets are assumed to be isothermal at all times. The droplet temperature as a function of time is determined by an appropriate heat balance. The calculations are useful in determining the significance of inelastic collisions between liquid droplets for complete combustion. Radiant heat transfer to moving liquid droplets is considered briefly.
