Abstract: Experiments were conducted in a rotating two-pass cooling channel with an aspect ratio of 2:1 (Dh=16.9 mm). Results for two surface conditions are presented: smooth and one ribbed configurations. ...

Abstract: In this paper, the effect of rib spacing on heat transfer in a rotating two-passage channel (aspect ratio, AR = 2:1) at orientation angle of 135 deg was studied. Parallel ribs were applied’ ...

Abstract: This paper experimentally investigated the rotational effects on heat transfer in a smooth two-pass rectangular channel (AR=2:1), which is applicable to the cooling passages in the midportion of ...

Abstract: This paper experimentally investigated the rotational effects on heat transfer in a two-pass rectangular channel (AR=1:4), which is applicable to the channel near the leading edge of the gas ...

Abstract: The gas turbine blade/vane internal cooling is achieved by circulating compressed air through the cooling channels inside the turbine blade. Cooling channel geometries vary to fit the blade ...

Abstract: Heat transfer and pressure drop have been experimentally investigated in an equilateral triangular channel (Dh=1.83 cm), which can be used to simulate the internal cooling passage near the leading ...
