Flow and Heat Transfer Behavior in Transitional Boundary Layers With Streamwise Acceleration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of streamwise acceleration on a two-dimensional heated boundary layer undergoing natural laminar-turbulent transition were investigated with detailed measurements of momentum and thermal ...
Effects of Criterion Functions on Intermittency in Heated Transitional Boundary Layers With and Without Streamwise Acceleration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Attempting to understand the mechanisms of momentum and thermal transports in transitional boundary layers has resulted in the use of conditional sampling to separate the flow into turbulent and ...
Intermittent Flow and Thermal Structures of Accelerating Transitional Boundary Layers: Part 1—Mean Quantities
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A conditional sampling technique was employed to separate the turbulent and nonturbulent parts of accelerated boundary layers undergoing laminar-turbulent transition on a uniformly heated flat ...
Intermittent Flow and Thermal Structures of Accelerating Transitional Boundary Layers: Part 2—Fluctuation Quantities
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The conditionally sampled fluctuation quantities of nonaccelerating and accelerating heated transitional boundary layers were analyzed. The results indicated that the values of u′, υ′, uv , and ...
