Slip flow over micron sized particles at intermediate Reynolds numbers

Rarefied flow behavior which is often appears in relatively low pressures for macro sized devices, might also occur at atmospheric or even higher pressures for the applications with micron-sized characteristic lengths. Spherical particles such as fuel droplets injected in combustion systems can experience rarefied flow to some degrees due to their micron-size diameters. This rarefied flow behavior can have dramatic influences on particle dynamics and heat transfer rate. Therefore, in this paper flow over an isothermal sphere in the slip flow regime 10-3
