... on boundary layer theory and provides insight into the effectiveness of a baffle in controlling growth of the thermal plume from the heat exchanger. The important physical mechanisms are the restricted entrainment and heat transfer to the storage fluid. For an adiabatic baffle as a base case, key design...

... models based on the resolution of the boundary layer equations have been developed ( 4 ). According to the boundary layer approximation, the flow field is divided into the inner and outer regions. The height of the inner region is chosen to give a balance between the horizontal pressure gradients...

... of dividing the blades of the wind turbine into two-dimensional airfoil sections and predicting the total noise emission as the sum of the contribution from each blade element. Input is the local relative velocities and boundary layer parameters. These quantities are obtained by combining the model...

... present on rotating HAWT blades. Previous analyses of rotationally augmented flow field data from the UAE wind tunnel test 16 17 show that normal force and boundary layer topology both respond strongly to LFA variations. In the current study, this LFA dependency needed to be suppressed in order...

... analyzed to identify boundary layer separation and shear layer impingement locations. Separation and impingement kinematics were then correlated with normal force behavior. Results showed that rotational augmentation was linked to specific separation and impingement behaviors, and to associated three...
