| Research Abstract |
THIS RESEARCH HAS TAKEN THE DEFORMATION PROCESS OF BREAKING WAVE IN RELATION TO INNER MECHANISM ON THE SLOPE AND IS THE PURPOSE OF ESTABLISHMENT OF NUMERICAL METHOD FORMED A PART OF PHENOMENON FROM DEFORMATION TO BREAKING WAVE.
1. THEORETICAL RESEARCH (1). IT IS PRESENTED THE NUMERICAL ANALYSIS MODEL IN CONNECTION WITH STUDY THE BREAKING WAVE ON THE SLOPE AND MAKES A CLEAR THE ANALYSIS METHOD BY FINITE ELEMENT.WE ESTIMATE THE ENERGY DISPERSION OF BREAKING WAVE WITH REYNOLDS STRESS OF PRANDTL TYPE,IN ADDITION WEWE TAKE A METHOD IN CONTINUTY EQUATION INCLUDED AN AIT PRESSURE THAT THE BREAKING WAVE COMES WITH AN CONTINUOUS AIR BUBBLE.IN COM-PARISON WITH EXPERIMENT,WE KNOWN A GOOD CALCULATIVE AGREEMENT THAT THE WAVE HEIGHT CORRESPONDS TO SLOPE GRADIENT AND STEEPNESS. (2) WE APPLIED A SMAC METHOD FOR MORE EXACT CALCULATION THROUGH BREAKING WAVE PHENOMENON,BECAUSE THERE IS A NONLINEAR AND UNSTANDING WAVE.WE MODIFIED SMAC METHOD,SO THE PRESENT SMAC METHOD CAN CAL-CULATE A DISTURB MECHANISM AFT

ER BREAKING WAVE.THIS CALCULATION SYSTEM USE A F.E.M RESULT DEVELOPED BY AUTHOR.THE CALCULATED RESULT GOOD AGREE WITH AN EXPERIMENTAL RESULT,WE DID A QUANTITATIVE CALCUL-ATION ABOUT BREAKING WAVE AND VOTEX. (3). WE DEVELOPED THE METHOD TO ANALYZE DIRECT F.E.M FOR CONTROL EQUATION OF TURBULENT FLOW ON BASE OF MIXTURE LENGTH THEORY TO PROBLEM OF THE WAVE BOUNDARY LAYER,WHICH EVALUATED QUANTITATIVELY THE EFFECT OF WAVE FINITE AMPLITUDE AND INERTIA TRANSFER TERM.NEXT,WE DEVELOPED F.E.M METHOD TO INTRODU-CE ENERGY DISPERSION AN OBJECT OF VOTEX EQUATION.THIS METHOD USED A CALCULATION THE TURBULENT BOUND-ARY LAYER ON THE RIPPLED SAND BEDS,WHICH CALCULATED THE PROPERTY OF DISTURB MECHANISM,THERE IS A GOOD AGREE BETWEEN NUMERICAL METHOD RESULT AND EXPERIMENTAL RESULT.
2. EXPERIMENTAL RESEARCH WE DID EXPERIMENT AN OBJECT OF BREAKING WAVE DEFORMATION PROCESS ON THE SLOPE. WE TAKE A VIDEO,EST-ALISH A PORTRAIT ANALYSIS SYSTEM,ANALYZE A INNER QUANTITY AND GET A COMPARATIVE DATA IN COMPARISON TO NUMERICAL ANALYSIS.WE INVESIGATE BREAKING WAVE DEFORMATION IN RELATION TO TRANSITION OF ALL QUAN-TITY.
