MULTIFORM PARTICLE-FLOW INTERACTION IN A CARRYING CONTINUUM GAS (REVIEW)
要約
The worldwide literature devoted to theoretical and experimental investigations of mass, energy, momentum, and angular momentum transfer between a separate solid particle and a flowing gas is reviewed and briefly analyzed. In particular, the most examined spherical particle is considered as a base case. The next step in shape complication is a spheroid (oblate or prolate ellipsoid). Data on irregularly shaped particles are the poorest. The most useful and tested expressions are recommended for drag and lift force coefficients, retarding and stall torques, and the Nusselt number as a function of conventional and rotational Reynolds and Prandtl numbers. The presented data can be useful in investigating the problems of aircraft icing in drop-crystal clouds, engine failure in gas-dust volcanic emissions zones, blockage of Pitot tube channels (airspeed instrument) due to particles of natural origin in the vicinity of airports, and the process of surface sandblasting optimization.
