Pool boiling heat transfer on horizontal metallic foam surface with crossing and single-
directional V-shaped groove was experimentally investigated at atmospheric pressure using
deionized saturated water as the working liquid. Boiling patterns were captured using a high
speed camera. The porosity of studied copper foam was fixed as 0.95. Thirty test samples
categorized into three groups were studied. The influences of crossing V-shaped groove
array configuration, single-directional groove width, and number on the heat transfer …

Pool boiling heat transfer on horizontal metal foam surface with U-shaped and V-shaped
groove configurations was investigated experimentally in deionized water at atmosphere
pressure. The boiling patterns were gained with a highspeed camera. The foam porosity,
foam thickness and pore density were fixed as 0.95, 2 mm, and 130 pores per inch,
respectively The U-shaped and V-shaped grooves were manufactured in the studied foam
samples with three widths (1, 2, and 3 mm) and three groove number values (1, 2, 3) The …
