Description

Critical Heat Flux Apparatus is consists of a cylindrical glass container containing distilled water. The heating surface is in the form of a Nichrome heating wire completely submerged in the water. Thermometers are provided to measure the temperature of water in the container, variac is provided to supply electrical input to the test heating wire.

Two successive regions of pool boiling phenomenon namely:

• • • Natural convection boiling and accompanies the
    • Nucleate boiling.

Other Details:

• • • Can be visualized up to the critical heat flux point which is attained by slowly increasing the input to heater by the dimmerstat. At the critical heat flux point, the wire melts indicating maximum heat flux position. Vend I can be recorded at critical heat flux point.
