N2 - In many different applications, non-stationary liquid droplet evaporation phenomenon works as a fundamental. An accurate prediction of heat and mass transfer on non-static droplet is required for design. Ranz-Marshall analogy combined with the Stagnant film Model is utilized method of predicting single non-stationary high mass transfer rate droplet evaporation, but there are several problems regarding to the method such as Lewis number more than one, static film width, and not simultaneously calculates heat and mass transfer. In this paper, A new approach to Stagnant Film Model and its new introduced constant is briefly discussed. The value of C1 and C2 is investigated by comparing 2-butanol evaporation numerical simulation with experimental data. The New Approach deviated less when predicting radius while both still failed to predict changes in temperature. The appropriate value of C1 on predicting the right radius varied between -0.010 to -0.035 while the value of C2 is -4 × 10-8. For different set-up variables, the value of C1 differs. Therefore, the value of C1 supposed be a function that can be furtherly investigated with the following research on other substances.
