Hello guys, My name is Pavan…Iam doing my Master’s in my local university… Presently iam doing my project in thermal stream…I need your help regarding the project…My project is about enhancement of heat transfer by employing double sinusoidal ribs in the double pipe heat exchanger…iam new to simscale …can you please help in this project…Here iam attaching the reference of single sinusoidal rib on the pipe…But we need double sinusoidal rib…And need to find wheather heat transfer coefficient is increasing or not…
Hi Pavan,
Welcome to Simscale, sounds like you are a mechanical engineer with a fair bit of work ahead of you 
Ok, I’m no in expert in thermo, but here are a few links that might assist, well hopefully this info at least gets you started;
Thermal Analysis, Thermomechanics & Heat exchanger tutorials
Interestingly I see wavy surfaces increases heat transfer https://journals.sagepub.com/doi/10.1177/1687814019872573
So I’ll be interested to see future simulations.
All the best
