Christensen, E H

Insulations which allow helium to flow upward along the near vertical heated conductor result in progressively reduced heat flux upward in the channel and non-cryostable conditions on the conductors in the higher field zones. Angles insulations were configured to induce the helium to flow laterally across the vertical conductor and way from the heated conductor which produced uniform and cryostable steady-state and transient heat flux along the high-field conductors in the verticle leg. Other results are detailed following the description of the test procedures and test results. The latter is presented in terms of transient heat flux data and wall-and-insulation helium gap effects. Subsequent discussion concerns the transient case and the comparison of peak nucleate boiling correlation with intensity of heating a rate of temperature rise.
