Critical heat flux and heat transfer transition for subcooled flow boiling
- Prairie View A and M Univ., TX (USA)
The emphasis in the engineering development of fusion reactor components has been on material development. If high heat fluxes are to be accommodated with the present emphasis, low-pressure thermal data will be needed. The objectives of this experiment were to (1) expand the critical heat flux, W/cm{sup 2} data base near 4.0 kilowatts cm{sup 2} and heated coolant channel length divided by coolant chamber diameter near 100.0 (near-term application), (2) add low-pressure quantitative data to our existing knowledge of the qualitative influence of coolant exit pressure on CHF, and (3) provide thermal data in a region applicable to high heat flux components for assessing existing and evolving CHF and local heat transfer coefficient correlations (long-term).
