A pulsating round jet having a constant average mass flow rate may increase heat transfer in comparison to a steady jet impinging on a surface. However, while several studies have focused on the heat transfer, flow field characteristics remain poorly

Heat transfer and flow field characteristics of a pulsating round air jet, impinging on a flat heated target surface were measured and compared to those of a steady impinging jet. The jet was partially confined and the target surface stand-off distan

Flow in the wake of a sphere has been studied for at least the last hundred years. The three-dimensional (3-D) flow structure has been observed many times using dye visualization and prior to the direct numerical simulations by Johnson & Patel (J. Fl

Few studies have investigated the flow characteristics of jets impinging on dimpled surfaces that may increase or decrease their heat transfer capabilities. Here, particle image velocimetry (PIV) measurements have been performed on a round jet (diame

Nonspherical particles such as fibers are commonly dispersed by turbulent boundary layer flows encountered in industry as well as our daily living environment. Fiber length has an effect on the orientation, translation, and rotation of fibers. In thi

The flow field in the sphere wake may be affected by roughness patterns such as those found on pine cones. These may enhance pollination by generating favorable flow patterns that capture conspecific pollen. A combination of time-resolved particle im

Dimpled surfaces may enhance or decrease heat transfer compared to smooth surfaces. Here, the flow field of a round, axisymmetric air jet (diameter D) impinging on smooth and dimpled target surfaces (positioned at H/D ≈ 5) was measured using partic

Impinging jets are widely used in cooling applications. Here, particle image velocimetry measurements were performed to study the flow field (focusing on the wall jet) and vortex characteristics of a round air jet, impinging on a flat surface at thre
