Accurate prediction of critical heat flux (CHF) is very important for design and operation of various heated equipments such as evaporator, fuel cell cooling system, nuclear reactor, etc.CHF experiments were performed to study the R134a CHF characteristics in a horizontal copper tube with 2.1 mm inner diameter under different hypergravity and over 1000 data points were obtained.
