AbstractWe present algorithms for fast computation of phase functions of atmospheric clouds and for stochastic simulation of such optical phenomena as fogbows, glories, coronas and halos. Using the developed numerical algorithms and software, we analyze optical phenomena for several cloud and fog models.

Line Contacts

A fast calculation model for the pressure distribution in EHL line contacts between rough surfaces is presented. Comparison between the results obtained from the model calculation and numerical simulation shows that, under heavily loaded conditions, the present model gives very accurate predictions of the pressure distribution for both deterministic and random transverse surface roughness. Since the model is based on the superposition of pressure fluctuations, the applications of this model are restricted to heavily loaded contacts.
