The Critical Heat Flux Apparatus is developed to study the maximum heat flux during boiling before transition to film boiling occurs. It includes a heating element, thermocouples, digital temperature indicator, and power-control system. Students can plot boiling curves and identify the point of critical heat flux for various fluids. This experiment strengthens understanding of two-phase heat transfer, fluid dynamics, and energy efficiency. Suitable for engineering colleges, polytechnic institutes, and ITIs, the equipment is durable, user-friendly, and provides accurate performance data for boiling studies.
