1. In order to fix ideas, the values of At/Aw and Ac/Aw for the present test react·:Cve-hetpipes are given in Table 1. The test values of· fLt/0 were in the range 0-10, depending upon operating conditions and the appropriate selection of transport tube length (in view of the fact that vapor transport, generation, and condensation occur simultaneous in portions of the test reactive-hear- pipes the length can only be approximated).
2. Configuration: 2 layers of 100 mesh screen at 1200 K, maximum exposed wick height. H-L, is given Lis zero by definition in thiF arrangementtNoviscouslosseseffect of fLt/D becoaes pronounced at high heat fluxes. The results at fLt/D • 10 at 1100 K illustrate cholt:lng in the vapor transport tube, where a maximumheat flux is reached irrespec ttve of the temperature drop across the syatea. The viclt beat flux for choked flow increaaea as fLt/D increases and the reference temperature decreases.
