Experimental and Numerical Investigation of Turbulent Heat Transfer due to Rectangular Impinging Jets
Due to their efficient heat and mass transfer potential, impinging jets have received attention in various applications. Heat transfer and flow characteristics of rectangular turbulent impinging jets issued from a 24:1 aspect ratio and 24:1 contraction ratio nozzle were investigated experimentally …

A First Complete Approach to Address Model Error in Computational Turbulent Heat Transfer
The challenge of turbulent heat flux has plagued the CFD modeling community for decades. A systemic dearth of adequate data has forced modelers to heavily rely on intuition and ad hoc reasoning to justify modeling choices. Many turbulence modelers believe that error in CFD temperature prediction …

Gas heat transfer in a heated vertical channel under deteriorated turbulent heat transfer regime
… Fast Reactor (GFR). Due to its high surface heat flux and low coolant velocities under natural circulation in post-LOCA scenarios, the capability of turbulent gas flow to remove heat from the GFR core can be impaired by either a buoyancy effect or an acceleration effect. These phenomena lead …

Turbulent heat transfer in a trapezoidal channel with transverse and v-shaped ribs on two opposite walls
This study investigates the turbulent heat transfer and friction in a trapezoidal channel with opposite walls roughened with transverse and v-shaped ribs. The roughened channel depicts the internal cooling passage of an aerofoil near the trailing edge. The various configurations investigated for …

Impact of an artifical circulation device on the heat budget of an ice-covered mid-latitude lake
… the impact of artificial circulation on the heat budget of a small mid-latitude ice-covered lake. The heat transfer algorithm developed by Patterson & Hamblin (1988) for high latitude lakes was extended to include the impacts of snowmelt due to rain, sediment heat transfer, snow-ice …

Laminar and turbulent convective heat transfer over bodies at an angle of attack
… to develop methods for calculating laminar and turbulent heat transfer over bodies of revolution at angles of attack. These methods are restricted to hypersonic flows over bodies with highly cooled walls. A method is presented for determining the surface inviscid streamline geometry and …

A frequency domain analysis of surface heat transfer/free-stream turbulence interactions in a transonic turbine cascade
The relationship of time-resolved surface heat flux to the turbulent free-stream flow over a turbine blade is investigated. Measurements are made in a transonic linear cascade with a modem high pressure turbine blade profile. Time-resolved direct heat transfer measurements are made with Heat Flux …

The Physical Mechanism of Heat Transfer Augmentation in Stagnating Flows Subject to Freestream Turbulence and Related Studies
The mechanism of heat transfer augmentation due to freestream turbulence in classic Hiemenz stagnation flow was studied experimentally for the first time using time-resolved digital particle image velocimetry (TRDPIV) and a new thin film heat flux sensor called the Heat Flux Array (HFA). Unique …
