      Hai..


      Problem Specification


      A fluid flows through a solid region where a transient heat source is present. The cp value of fluid depends on temperature.


      How to plot the amount of heat absorbed by the fluid over time in cfd post.

      That would be theat released by
      The solid region in contact with fluid. Say heatflux at contact interface on the fluid side.

      Sorry. I could not understand your answer. Can you explain it a bit more?

      In Fluent or CFX you have your Fluid passing though a solid region. Imagine now both are meshed and part of your model. CFX or Fluent will build up a sort of an interface or similar between both. At that interface you can look for the heat flux transferred between the solid body and fluid region. Look after the variable Heat Flux in Post which you can integrate along the Wall/Interface/Contact.


       


      For more information you need to post some more details here so that we can be more specific here.

      A quick check in Fluent would be Postprocessing - Reports - Fluxes - Heat transfer rate
