Numerical investigation of heat transfer from a heated oscillating cylinder in a cross flow

Heat transfer enhancement in a straight channel via a rotationally oscillating adiabatic cylinder

“…Their investigations on flow kinematics led to two distinct studies that focused on the influences of vortex dynamics on mixing and heat transfer [3,4]. Although heat transfer from a transversely oscillating heated structure has been studied before [5e7], investigations on channel heat transfer enhancement due to an oscillating adiabatic structure are rather limited [4,8,9]. Celik et al utilized the vortex shedding mechanism from a transversely oscillating adiabatic circular cylinder to enhance heat convection from uniformly heated channel walls [4].…”

Convective heat transfer enhancement in a parallel plate channel by means of rotating or oscillating blade in the angular direction

“…They found that heat transfer enhancement could be achieved by increasing oscillation angle with a frequency equal to 0.8 of the cylinder natural frequency. Fu and Tong [12] studied heat transfer characteristics of a heated transversely oscillating cylinder and observed that, by approaching of the oscillating frequency of the cylinder to the natural vortex shedding frequency, heat transfer rate was enhanced remarkably. They also in [13] carried out a numerical simulation to study the effects of transversely oscillating cylinder on heat transfer from heated blocks in a channel.…”

Numerical study of electrode bank enhanced heat transfer

“…In terms of heat transmission characteristic [17][18][19], the local heat transfer coefficient in terms of the local Nusselt number of laminar sublayer near the surface which can be applied in this work is simply given by…”
