The Leidenfrost point signifies the access of abiding blur boiling. It represents the point on the baking ambit area the calefaction alteration is at the minimum and the apparent is absolutely covered by a breath blanket. Calefaction alteration from the apparent to the aqueous occurs by advice and radiation through the vapor. In 1756, Leidenfrost empiric that baptize aerosol accurate by the breath blur boring clear as they move about on the hot surface. As the apparent temperature is increased, radiation through the breath blur becomes added cogent and the calefaction alteration increases with accretion balance temperature.
The minimum calefaction alteration for a ample accumbent bowl can be acquired from Zuber's equation,[7]
{{\frac{q}{A}}_{min}}=C{{h}_{fg}}{{\rho }_{v}}{{\left[ \frac{\sigma g\left( {{\rho }_{L}}-{{\rho }_{v}} \right)}{{{\left( {{\rho }_{L}}-{{\rho }_{v}} \right)}^{2}}} \right]}^{{}^{1}\!\!\diagup\!\!{}_{4}\;}}
where the backdrop are evaluated at assimilation temperature. Zuber's constant, C is about 0.09 for best fluids at abstinent
