Abstract: When the wind stress and the destabilzing buoyancy flux of surface coolingsimultaneously act on the water surface of lakes and reservoirs,complicated mixingphenomena take place due to the combined action of mechanical and thermal stirring.To simulate such a situation,the authors devised an experimental model as shown inFigure 1(a),where the thermal stratification was modeled as a two-1ayer system;the mechanical turbulence and thermal convective motions were driven by means ofan oscillating grid and a botton plate heater,respectively.We succeeded in ex-perimentally formulating the mixingaw¹),which was applied to predict the thermalstructure of practical reservoirs²).The present work seeks to theoreticallyanalyze the turbulent structure in this system and examine the heat and masstransport process.
