Abstract

THE SELECTION OF THE TYPE OF TURBULENCE MODELS HAS AN IMPORTANT IMPACT ON THE PERFORMANCE OF THE NUMERICAL MODELS FOR FLOW SIMULATION IN THE COMPUTATIONAL FLUID DYNAMICS SOFTWARES. THIS RESEARCH IS CONDUCTED TO DETERMINE THE EFFECTIVENESS OF SINGLE-EQUATION MODEL OF TURBULENCE KINETIC ENERGY AND TWO-EQUATION MODEL OF K-EPSILON IN SIMULATION OF POSITIVE WAVE MOVEMENT CAUSED BY DAM FAILURE ON A MOBILE BED. THE RESEARCH METHOD INCLUDED THE NUMERICAL CALCULATIONS USING FLOW-3D SOFTWARE. THE RESERACH RESULTS SHOWED THAT K-EPSILON MODEL IS MORE ACCURATE IN PREDICTING THE PATTERN OF THE FLOW’S FREE SURFACE. BOTH MODELS HAVE THE SAME ACCURACY IN CALCULATING THE PROFILE OF THE NON-DIMENSIONAL DEPTH, VELOCITY AND ACCELERATION OF THE ADVANCING FRONT OF POSITIVE WAVE. NEITHER MODEL COULD PREDICT WELL THE PROFILE OF MOBILE SEDIMENT BED. THE FINAL CONCLUSION IS THAT K-EPSILON TURBULENCE MODEL HAS HIGHER EFFICIENCY IN SIMULATION OF FLOW IN DAM FAILURE ON THE MOBILE BED.
