Summary: | The effect of a magnetic field on critical heat flux-CHF in liquids metal is discussed within framework of Helmholtz instabilities. Utilizing a classical simplified model and considering the effect of magnetic field, an analytical expression for the critical heat flux-CHF was derived. Combining this equation with the expression for the heat transfer coefficients deduced in previous work yields an analytical equation for the temperature difference at the minimum. The above equations to predict an enhancement for critical heat flux which is reasonable due to stabilizer effect of magnetic field, however, disagree with the available experimental measurements made on mercury where a indication of the premature onset of critical heat flux with a horizontal magnetic field was observed. Therefore, the reason for this is not clear and the behavior of the CHF in the same manner that the bubble frequency is still unresolved. |
