Application of the "Law of the Wall" to Predict the Heat Transfer for Turbulent flow in a Rod Bundle

봉다발의 열전달 예측을 위한 "벽면의 법칙(Law of the Wall)" 적용

In this study, an analytic model is developed to predict Nusselt numbers for turbulent flow in a rod bundle. Flow channel area is divided into several element channels, and simple algebraic equations of universal velocity and temperature profiles are integrated over each element channel. The integral equations are then added to yield an analytic expression for the nusselt number of a rod bundle. The analytic model reasonably predicts the available heat transfer data.
