The boiling flow instabilities in a horizontal hairpin tube have been studied experimentally. In the experimental investigations, steady-state characteristics of the flow, pressure drop oscillations, and density wave type oscillations were observed. Freon-113 was used as the test fluid. Steady-state and oscillation parameters such as inlet pressure, pressure drop of the system, mass flow rate, tube wall temperatures, and fluid temperature were recorded. Experimental results are presented in the form of system pressure drop versus time. Experimental results are discussed. The experimental ranges were as follows: system exit pressure p = 2-4 bar; mass flow rate G = 1-30 Kg/min; heat input Q = 6900-9900 w.
