Heat transfer from a vibrating cylinder

Heat transfer past rotationally oscillating circular cylinder heated with time‐periodic pulsating temperature in a uniform flow

“…Studying oscillation of isothermal cylinder in fluid flow is a very important aspect as it has contribution to enhancing the heat transfer process. Many researchers got inspired by this idea and studied the heat transfer with transverse oscillations 4–10 and streamwise oscillations 11–14 . However, rotational oscillation has an edge over transverse and stream‐wise oscillations for various applications with very difficult space constraints.…”

“…Many researchers got inspired by this idea and studied the heat transfer with transverse oscillations [4][5][6][7][8][9][10] and streamwise oscillations. [11][12][13][14] However, rotational oscillation has an edge over transverse and stream-wise oscillations for various applications with very difficult space constraints. Also, it is important to note that these studies have produced conflicting results.…”

Combined active-passive heat transfer enhancement for a partial superhydrophobic oscillating cylinder

“…Saxena and Laird [20] examined an oscillating cylinder in an open water channel and obtained a 60 percent increase in heat transfer coefficient. In experimental studies by Leung et al [21] and Gau et al [22], the heat transfer magnitude was seen to be affected by the oscillation amplitude and frequency. Fu and Tong [23] investigated the flow and heat transfer characteristics of a transversely oscillating heated cylinder and also found the heat transfer rate to be significantly enhanced in the lock-in regime.…”

The thermal characteristics of a hot wire in a fluctuating freestream flow

“…The experiments indirectly support the contention that the thermal response of the hot wire is the overriding factor for determining the overall response of the hot-wire system and not the (electronic) CTA unit per se. Kezios and Prasanna (1966), Saxena and Laird (1978), Leung et al (1981) and Cheng et al (1997a,b) have conducted extensive experimental and numerical studies to investigate the effect of the transverse oscillation of a cylinder on forced convection. They set a cylinder to oscillate transversely in the direction normal to the flow stream, and found that nonlinear interaction occurs particularly as the cylinder oscillation frequency gradually approaches the natural frequency of vortex shedding.…”
