Abstract Experiments were performed to study the effects of surface wettability on flow boiling of water at atmospheric pressure. The test channel is a single
rectangular channel 0.5 mm high, 5 mm wide and 180 mm long. The mass flux was set at 100 and 120 kg/m2 s and the base heat flux was varied from
30 to 80 kW/m2. Water enters the test channel under subcooled conditions. The sample surfaces are titanium (Ti) and diamond-like carbon (DLC)
surfaces having a contact angle of 49° and 63°, respectively. The experimental results show different flow patterns that impact the heat transfer
significantly.… More >
