Heat Transfer in laminar flow caused velocity field varied?

Heat Transfer in laminar flow caused velocity field varied?

Heat Transfer in laminar flow caused velocity field varied?

(OP)
Hello,
I have questions about heat transfer in laminar flow, my model is a slab with a pipe runs through it, the slab will have heat conduction, and the water will run through the pipe, the Re# of water is about 1200.  When I just analyzed water velocity filed alone without heat transfer, the water velocity field will stay constant after passed develop length, but once I coupled it with heat transfer, the water velocity will fluctuate along the flow direction as well as water temperature.  Is this caused by temperature difference? because water property and velocity are depended on temperature?

Thank you for help

RE: Heat Transfer in laminar flow caused velocity field varied?

The velocity shouldn't be affected by the heat transfer.  It's basically a function of the area of the opening and the flow rate of the fluid (which is usually a funtion of the pump.) You haven't provided enough information for me to go further.

Is this a modeling problem or are you actually experiencing a velocity fluctuation problem?
