NATURAL CIRCULATION EXPERIMENTS IN AN OSCILLATING FORCE FIELD
Resumo
A natural circulation vapor generating
loop is operated on a vertically oscillating carriage
which simulates ship heaving motion. Mass
flow rate, tube wall temperatures, burnout heat
flux, and vapor void fraction are measured. Flow
rate, wall temperature, and void fraction fluctuate
in response to the motion, while burnout heat
flux is reduced. The greatest deviations from
steady flow values occur when there is resonance
between motion frequency and natural flow oscillation
frequency.
