I need a coolant convection coefficient ''library'' or suggestions to calculate this coeff. To setup some FEM simulations of turning machining processes. Thanks a lot for any help or suggestion.
Dear Adnan, I can't help you but may recommend you to get contact with Prof. Dr. Sadık Kakaç of TOBB University. Please tell him that I recommended him for you,
Best Regards
The question is not so clear. As far as I understand you need a convection heat transport coefficient h, for a given coolant flowing on a solid surface. Can you confirm that. ? If so, what do you want to simulate exactly ? The flow ? Heat transport by conduction in the solid ? Both ?
Conventional ''flooding'' processes, dry cutting and Minimal Quantity Lubrication processes use different volumes of cutting fluids. The goal of my project is to eliminate the flood cooling with some enviromentall friendly cooling and lubrication systems like the MQL, which uses a very small amount (up to 500ml/h) of oil-water mixed with compressed air and fed to the cutting interface as an oil mist.
For FEM simulation of cutting forces, temperature distribution, tool wear, residual stresses, etc. of machining-metalworking processes like turning, milling, drilling, etc. with different coolant metalworking fluids I need some support about the heat transfer coefficient of the coolant fluids.
The question was how to estimate or calculate the heat transfer coefficient for different fluids or oil mist without real experimental setup? Is it possible to calculate them without the real experiment?
