Hello,

 

I am try to use the calculation method defined in the paper published by Jimmy D Kumana and Samir P Kothari to Predict Storage tank heat transfer precisely. 

Here is the link of a post in this forum -

is it possible to use this calculation method with a vertical, outside, atmospheric storage tank with an agitator, which adds forced convection component in the calculation.

Will it be correct to replace the Natural convection parts in the calculation with a forced convection?

here are some articles showing how to calculate the inside heat transfer coefficient of tank with an agitator.

please share your thoughts. it will be really helpful.

 

Thank you,

There are many variables in calculating storage tank heat transfer. In my opinion, precise and accurate calculations would require tuning the parameters against a real-world dataset. An easier task would be to calculate a conservative heat transfer to consider the worst case in whichever direction was important. I have calculated storage tank heat transfer when designing compressors or refrigeration systems for cryogenic boiloff and for specifying molten polymer tank heat tracing, but I never relied completely on the accuracy of my calcs and always included a generous safety factor.

Hi,

Should be possible, considering heat transfer correlation for forced convection instead of natural convection (in the liquid part) together with heat generated with the agitator during rotation. If possible, start a model and compare with data on site. This will tell how much margin is needed.

Good luck

In addition, you may also need to account for external heat effects, such as heat exchange to/from ambient and solar insolation effects.
