Hello everyone,
Can anyone tell me on what factors does the heat transfer co-efficient depend upon. I am trying to do simulate two types of Quenching 1. Quenching of High Carbon Steel in an Oil Bath 2. Quenching of High Carbon Steel in a water jet (mixed with polymers) I need to find the HTC in each case. Hence I wanted to know what are all the parameters (however minuscule or general) , the HTC depends upon. Any leads would be highly appreciated. Thank YOu |

There might be some experimental research papers dealing with the quenching you describe. Try to google that out.
You might already know this, but the HTC values are likely strongly dependent on the flow velocity at the fluid-solid interface. Bubble formation would likely have a strong insulating effect. Other than that the fluid heat capacity could play a role. |

Generally, a heat transfer coefficient should be determined experimentally. Theoretically, knowing the surface temperature, , and the temperature of the fluid measured prior to quenching, , heat transfer coefficient can be determined by solving the following equation: where is the surface temperature of the solid and is the volume of the solid. |
