Direct Numerical Simulation of Subcooled Nucleate Pool Boiling
With the long-term objective of Critical Heat Flux (CHF) prediction, a Direct Numerical Simulation (DNS) framework for simulation of subcooled and saturated nucleate pool boiling is developed. One case of saturated, and three cases of subcooled boiling at different subcooling levels are simulated. Grid refinement study is also reported. Both boiling and condensation phenomena can be computed si...
متن کاملHighly subcooled pool boiling heat transfer at various gravity levels
A microscale heater array 2:7 mm 2:7 mm in size along with a video camera was used to provide subcooled pool boiling heat transfer measurements at gravity levels ranging from 1.8g to 10 g. The fluid was FC-72 at 1 atm and subcooled by nominally 36 C for all cases. A Terrier–Orion sounding rocket and the KC-135 aircraft were used to provide the microgravity and low-g environments, respectively. ...
متن کاملHeater size and heater aspect ratio effects on subcooled pool boiling heat transfer in low - g
Pool boiling heat transfer measurements using heaters of varying aspect ratio were obtained in low-g (0.01 g ± 0.025 g) aboard the KC-135 aircraft. The heater aspect ratio was varied by selectively powering 2 · 2, 2 · 4, 2 · 6, 2 · 8, and 2 · 10 arrays of heaters in a 10 · 10 heater array containing individual heaters 0.7 · 0.7 mm in size. Electronic control circuitry was used to maintain an is...
متن کاملSubcooled Pool Boiling Experiments on Horizontal Heaters Coated With Carbon Nanotubes
Pool boiling experiments were conducted with three horizontal, flat, silicon surfaces, two of which were coated with vertically aligned multiwalled carbon nanotubes (MWCNTs). The two wafers were coated with MWCNT of two different thicknesses: 9 m (Type-A) and 25 m (Type-B). Experiments were conducted for the nucleate boiling and film boiling regimes for saturated and subcooled conditions with l...
متن کاملForced Convection Subcooled Boiling of Binary Mixtures
A mode based on an additive mechanism of heat transfer is proposed for forced convection subcooled boiling of binary mixtures. The contributing modes of heat transfer are: (i) the heat transferred as latent heat by the rising bubbles, (ii) the heat transferred as the heat contained in the superheated thermal layer that is removed from the surface in the wake of the rising bubbles and (iii) the ...
