Class
Foam::wallBoilingModels::TDNBModels::Shirai
Description
Temperature of departure from nulceate boiling correlation.
References:
\verbatim
Shirai, Y., Tatsumoto, H., Shiotsu, M., Hata, K.,
Kobayashi, H., Naruo, Y., & Inatani, Y. (2010).
Boiling heat transfer from a horizontal flat
plate in a pool of liquid hydrogen.
Cryogenics, 50(6-7), 410-416.
DOI:10.1016/j.cryogenics.2010.04.001
\endverbatim
Usage
Example of the model specification:
\verbatim
TDNBModel
{
// Mandatory entries
type Shirai;
Tc <scalar>;
Pc <scalar>;
}
\endverbatim
where the entries mean:
\table
Property | Description | Type | Reqd | Deflt
type | Type name: Shirai | word | yes | -
Tc | Critical temperature | scalar | yes | -
Pc | Critical pressure | scalar | yes | -
\endtable
Note
- Correlation based on fiting data from Fig 11 from above references.
- Suitable for liquid Helium, Nitrogen, Oxygen and Hydrogen.
