RISEffects of Attack Angle and Relative Thickness of Novel Wing-Shaped Turbulators on Turbulent Hydrothermal Performance in a Two-Pass Square Channel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work aims to combine the effects of the near-wall and core flow disturbance by proposing novel wing-shaped turbulators. The new turbulators are fabricated with the fused deposition modeling (3D printing) technology. ...
Particle Image Velocimetry Measurements in a Two Pass 90 Degree Ribbed Wall Parallelogram Channel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A parallelogram channel has drawn very little or no attention in the open literature although it appears as a crosssectional configuration of some gas turbine rotor blades. Particle image velocimetry (PIV) is presented of ...
Thermal Performance of a Radially Rotating Twin Pass Smooth Walled Parallelogram Channel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental study was performed to measure the detailed heat transfer distributions, Fanning friction factors (f), and thermal performance factors (TPF) of a radially rotating twinpass parallelogram channel. Laboratory ...
Isolated and Coupled Effects of Rotating and Buoyancy Number on Heat Transfer and Pressure Drop in a Rotating Two-Pass Parallelogram Channel With Transverse Ribs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Detailed Nusselt number (Nu) distributions over the leading (LE) and trailing (TE) endwalls and the pressure drop coefficients (f) of a rotating transverse-ribbed two-pass parallelogram channel were measured. The impacts ...
Influence of Rotating Directions on Hydrothermal Characteristics of a Two-Pass Parallelogram Channel With Detached Transverse Ribs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The detailed Nusselt number distributions on leading and trailing endwalls together with the Fanning friction factors of a rotating two-pass parallelogram ribbed channel are simultaneously measured under forward and backward ...
