 May 28, 2019, 17:39 Parallel plate channel with staggered ribs #1 New Member   Edoardo Join Date: May 2019 Posts: 2 Rep Power: 0 Hi everyone ! I am studying the turbulent flow in a parallel plate channel equipped with staggered ribs. The shape of the ribs is trapezoidal, but front and rear edges are rounded (see attachment). I kindly ask you if someone could help me with some references that could indicate a correlation to compute Nu number in this particular geometry. All the refereces I've read are about square channel ( and not parallel plates ). In particular, I've seen in the available Nu correlations for square channels I have to use hydraulic diameter, that for a parallel plate could be computed as 2H. May be a reasonable assumption? Thank you for your attention Last edited by edoardobrunetto; May 28, 2019 at 17:59. Reason: adding clarification

Check a letter published by Foroozani et al. (2019) on Physics E. She has done some work on RBC with grooves.

Thank you for your answer Santiago, but it's not the geometry I am looking for
I am still looking for a reference in which someone has did a similar study, in order to validate my results.
