Abstract
Steady laminar flow past solitary spheroids and nonspherical droplets has been numerically analyzed. Specifically, interfacial transport properties such as surface pressures, interfacial velocities, shear stresses and separation angles as well as the resulting drag coefficients are evaluated for specified aspect ratios (0.2 ≤ E = b/a ≤ 1.0) and intermediate gas stream Reynolds numbers (40 ≤ Re ≤ 120). For one case, it was determined that the use of the traditional spherical-droplet assumption would result in a 30 percent underprediction of the total drag coefficient.
