Experimental Study on the Coupling Wake Effect Due to the Motion and Buoyant Jet of the Vehicle in Thermohaline Double Stratified Environment
Based on the stratified flow test pool,a mobile multi-channel thermal resistance sensor array was used to measure the underwater temperature field,and an infrared thermal imager was used to obtain the surface temperature field synchronously.An experimental study was carried out on the coupling effect of vehicle wake and buoyant jet in a thermohaline double stratified environment.The experimental results show that the surface effect of the vehicle wake mainly depends on the strength of the moving wake,while the diffuse buoyancy jet is inhibited by thermohaline stratification,which only affects the background water temperature distribution at the initial stage and near the discharge.With the increase of the speed,the disturbance of the moving wake to the background stratification is strengthened,while the influence of the buoyant jet is weakened.The thermal characteristics of the wake surface of the vehicle depend on the depth of the vehicle and are not sensitive to the initial velocity of the buoyancy jet.
