Abstract
The problem is the determination of the temperature and density
distribution in a steam atmosphere surrounding a falling droplet. Prom
the results thus obtained, the heat and mass fluxes are computed along
with their respective transfer coefficients. Numerical computation is
required and an explicit finite difference method is used in the
reduction of the energy and mass equations into finite difference forms.
The velocity distribution is obtained from the numerical solution of the
viscous flow around a droplet at a Reynolds number of 1000. Prom this
distribution, the eddy diffusivity distribution is obtained. The
droplet model used is that of complete mixing, that is, the droplet is
assumed to be vigorously mixed such that the temperature and density
profile in the droplet is uniform. Computed results are compared with
few available data and are found to be in good agreement.
