- •
Startup mechanism and thermal performance of a CLPHP is reported.
- •
Influence of pure fluids, water-based binary fluids and surfactant solutions are investigated.
- •
Startup heat flux is observed lower for acetone and higher for water compared to all other working fluids.
- •
Thermal resistance is observed to decrease with increase in heat input irrespective of working fluids.
- •
CLPHP is observed to perform better with acetone, water-acetone, water-45 PPM and water-60 PPM surfactant solutions.
