Sinusoidally curved channels

In the articles cited above, the studies were restricted to steady-state flows, and steady-state solutions could be determined for the range of Reynolds numbers considered. Experimental work on flow and heat transfer in sinusoidally curved channels was conducted by Rush et al. [121]. Their results indicate heat-transfer enhancement and do not show evidence of a Nusselt number reduction in any range... 

Flow in sinusoidally curved channels for Reynolds numbers up to 500 was studied by Garg and Maji [30]. Again, a finite-volume discretization was used.

A very-low-frequency sinusoid was superimposed on these spectral lines owing to channeling. This comes about by reflections from the window surfaces that contain the sample gas. These often result in a spike on the interferogram, which produces a superimposed sinusoid on transforming. Rather than removing the sinusoid from the entire data set, we fitted a smooth curve to the base line of each isolated set of lines treated.

Continuous lines are the fits from the theoretical models of two diffusion processes (dash and dash-dot lines denote the theoretical characteristic function curves down the sinusoidal and the straight channels, respectively) and the symbols ( , o) present experimental in-phase and out-of-phase characteristic function data, respectively.
