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: To understand the physics of volcanic ash impact on gas turbine hot-components and develop much-needed tools for engine design and fleet management, the behaviors of volcanic ash in a gas turbine combustor and nozzle guide ...

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: Accurately forecasting energy dissipation is critical to the hydraulic design of stepped spillways. In this study, support vector machine regression (SVR) was applied to estimate the energy dissipation of a stepped spillway. ...

Abstract: The performance of the anaerobic ammonium oxidation (ANAMMOX) process was investigated in two identical sequencing batch reactors (SBRs) [designated as SBR1 (tourmaline addition) and SBR2 (check reactor)] at nitrogen loading ...
