SMOOTH PARTICLE HYDRODYNAMICS SIMULATION OF SURFACE COATING

The simulation of plane impinging jets using the Lagrangian technique of smooth particle hydrodynamics is presented. In Section 1 the imping ement of a plane jet onto a stationary surface is considered for Reyno lds numbers 800, 4000, 8000 and Froude number 4. For each case, the he ight of the associated streams is measured and compared with both expe rimental and theoretical results. The agreement between these results is found to be close for most impingement angles. In the second sectio n, impingement onto a moving surface is considered for Reynolds number s of 50 and 800 and Froude numbers of 1 and 4. The preliminary results show that the moving surface can lead to some spatial height variatio n in at least one of the streams. (C) 1998 Elsevier Science Inc. All r ights reserved.
