So the heat exchanger will have 2 bodies , one is a cylinder in which water will be maintained at a constant temperature and into this volume will be inserted a helical coil (2 nd body)through which our fluid (which is to be heated) will pass. What kind of boundary condition should I use for outer body . Thank you.
