... degrees, respectively. The influences of various diameter ratios in addition to various attaching angles between Darrieus and Savonius rotors in the proposed design are numerically investigated. The Reynolds-Average Navier-Stokes equations in three dimensions along with the turbulence model of k-ω (SST...

Dynamics of Flow and Heat Transfer Around Two Circular Cylinders of Different Diameters in Tandem Subjected to Forced Convection

Rami Homsi, Md Islam, Yap Yit Fatt, Isam Janajreh
Proc. ASME. IMECE2021, Volume 7A: Dynamics, Vibration, and Control, V07AT07A037, November 1–5, 2021

... ≤ L/D d ≤ 8 and diameter ratios 0.5 ≤ D u /D d ≤ 2. The effect of heating on the flow is captured by modelling the thermophysical properties of the fluid fitted as polynomial functions of temperature. The flow features are visualized by plotting the streamlines and velocity magnitude contours...
