DISSIPATION OF WaveS IS AN IMPORTANT MATTER IN ENGINEERING DISCUSSIONS. IN SEISMIC DISCUSSIONS, FOR INSTANCE, HAVING INSIGHT INTO THE MECHANISM BY WHICH WaveS DISSIPATE IS INEVITABLE. Wave LOADING ON STRUCTURES IS ANOTHER IMPORTANT ISSUE. MANY STUDIES HAVE ALREADY BEEN CONDUCTED ON FLUID-STRUCTURE INTERACTIONS AS A RESULT OF SEISMIC DYNAMIC WaveS. SUMMERFIELD METHOD, WHICH IS BASED ON FINITE ELEMENT, IS A TYPICAL INNOVATION IN THIS REGARD. GIVEN THE CAPABILITY OF FINITE ELEMENT METHOD AND ALSO THE DISADVANTAGES OF IT, THIS METHOD HAS BEEN FOCUSED IN SEA-Wave LOADING AND IN modelING FLUID RANGE. IN THIS ARTICLE, RESEARCHER STUDIED Wave- STRUCTURE INTERACTIONS USING BOUNDARY CONDITIONS IN SPECIFIED TIME SPAN. IT IS RECOMMENDED THAT THIS PROBLEM BE PAID SERIOUS ATTENTION BY AUTHORS IN ORDER TO CONDUCT STUDIES THAT CAN HELP REVEALING HIDDEN ASPECTS AND INTRODUCE INNOVATIVE modelS.

INTRODUCTION: STUDYING Wave AND OCEAN HAS AN IMPORTANT ROLE IN THE WORLD TODAY. THANKS TO THE NUMERICAL Wave PREDICTION modelS AND APPLYING THEM IN THE WORLD SCALE WITH ACCEPTABLE ACCURACY, WE CAN FIND WORTHY INFORMATION ABOUT THE SEA STATE IN THE FOLLOWING HOURS. …

WIND WaveS, WHICH CAN TRAVEL BEYOND THE DIRECT EFFECT OF THE GENERATING FORCES, ARE REFLECTED BY BEACHES, BREAKWATERS, SHORELINE STRUCTURES AND SUBMERGED OR FLOATING OFFSHORE STRUCTURES. THE INTERACTIONS BETWEEN REFLECTED AND INCIDENT WaveS CONTRIBUTE TO THE CHARACTERISTICS OF THE Wave FIELD AND FLOW FIELD BENEATH THE WaveS. A LABORATORY STUDY CARRIED OUT TO CONSIDER THE REFLECTION CHARACTERISTICS FROM THE BEACH WITH A CONSTANT MILD SLOPE OF A Wave FLUME AND A model VERTICAL SEAWALL USING THE TWO DIMENSIONAL METHOD OF GODA AND SUZUKI (1976). AN EXTENSIVE SERIES OF EXPERIMENTS SET UP COVERING DIFFERENT REGULAR, IRREGULAR AND GROUPY WaveS TO FIND THE PERCENTAGE OF REFLECTED WaveS. TWO METHODS OF 1) AVERAGING THE REFLECTION COEFFICIENT COMPONENTS 2) USING THE POWER SPECTRA OF INCIDENT AND REFLECTED WaveS IN A SUITABLE RANGE OF FREQUENCY WERE EMPLOYED TO OBTAIN THE REFLECTION COEFFICIENTS. THE RESULTS SHOWED THAT IN BOTH METHODS THE PROPER HANDLING OF SPURIOUS SPIKES IS VITAL TO GET REAL RESULTS FOR REFLECTION COEFFICIENT. THE RESULTS ALSO SHOWED THAT THE RATE OF REFLECTION COEFFICIENT INCREASES WITH AN INCREASE IN FUNDAMENTAL Wave FREQUENCY. HOWEVER THE REFLECTION COEFFICIENT GET LARGER FOR GROUPY WaveS WITH LONGER DURATION.

INTRODUCTION: CHARACTERISTICS OF WIND WaveS ARE NECESSARY FOR ANY COASTAL ENGINEERING PROJECTS SUCH AS DESIGNING PORTS, COASTAL AND OFFSHORE STRUCTURES, ESTIMATING SEDIMENT TRANSPORT AND BEACH EROSION. PRESENCE OF LARGE NUMBERS OF MARINE STRUCTURES IN PERSIAN GULF WITHIN QESHM AND ….

THIS PAPER, FIRSTLY PRESENTS RESULTS OF IRAN’S SEAS Wave ENERGIES STUDIES. AND THEN DIFFERENT KINDS OF Wave ENERGY CONVERTERS ARE CONSIDERED AND THE BEST ONE IS SELECTED.AFTER THAT, THE CONDITIONS OF model ARE DESCRIBED AND THE RESULTS OF TESTS ARE PRESENTED. THE EFFICIENCY OF THE model IS %19.2 SO THE FULL SCALE OF IT IS SUITABLE FOR LOCAL USAGE.
