BOILING HEAT TRANSFER OF LIQUID HELIUM UNDER HIGH ROTATIONAL FIELD.

Author(s) : ISHII I.

Type of article: Article

Summary

HEAT FLUX IN LIQUID HELIUM IN A ROTATING SUPERCONDUCTING MAGNET WAS MEASURED UNDER THE ROTATIONAL SPEEDS OF 500 TO 3,600 RPM IN ORDER TO HELP ANALYZE THE STABILITY OF FIELD WINDING OF SUPERCONDUCTING TURBINE GENERATORS. MAXIMUM CENTRIFUGAL ACCELERATION AT THE LOCATION OF HEAT FLUX MEASUREMENT WAS 2,045 G. MEASURED MAXIMUM HEAT FLUX IN THE NUCLEATE BOILING REGION WAS INCREASED TO 2 W/CM2 AT THE ROTATIONAL SPEED OF 500 RPM ; IT CHANGED LITTLE WITH THE INCREASE OF ROTATIONAL SPEED ABOVE THIS LEVEL. IN THE FILM BOILING REGION, BOTH HEAT FLUX AND MINIMUM HEAT FLUX WERE INCREASED WITH THE INCREASE OF THE ROTATIONAL SPEED UP TO 3,600 RPM.
