Abstract

Accurate investigation of physical phenomena is one of the important challenges in engineering fields.The present study investigates a wet tank in which entrance of water is investigated in three cases.When the water wave moves into a tank, complex flow regimes are created. This complexity is mainly associated with different flow mechanisms during the entrance of water and propagation of waves at the bottom bed that should be modelled by means of NAVIER-STOKES EQUATIONS with free-surface capability and in 3D phase. Due to complexity and time consumption of NAVIER-STOKES EQUATIONS modelling, SHALLOW WATER EQUATIONS are used with the assumption of hydrostatic pressure. First case is about efflux over a wet bed. Second, water influx from the middle top is investigated and then influx from top edges is modelled. A dimensionless number is introduced for each case based on water velocity, gap length and drop height which shows acceptable domain for appropriate compatibility between results. Finally, results of NUMERICAL MODELLING are compared with Navier-Stokes solutions which are obtained from STAR-CD SOFTWARE. Results show admissible compatibility with each other based on observations and inspections.
