Expansion Ratio Effects on Three-Dimensional Separated Flow and Heat Transfer Around Backward-Facing Steps

Autor: Kazuaki Sugawara, Hiroyuki Yoshikawa, Terukazu Ota, Aya Kitoh

Publikováno v: Journal of Heat Transfer. 129:1141-1155

Direct numerical simulation methodology clarified the three-dimensional separated flow and heat transfer around three backward-facing steps in a rectangular channel, especially effects of channel expansion ratio ER upon them. ER treated in the presen

Application of a High Order LES Approach to the Redistribution of Inlet Temperature Distortion in a Turbine

Autor: Aya Kitoh, Debasish Biswas

Publikováno v: ASME 2013 Gas Turbine India Conference.

The demand of an increase in the cycle performance of today’s gas turbines creates severe heat loads in the first turbine stage, since higher operating temperatures are required. The mean flow temperature is usually well above the limit supported b

Three Dimensional Thermo-Fluid Analyses on Convective Heat Transfer and Friction Loss in Micro/Mini Channel Based on High Order LES Model

Autor: Debasish Biswas, Aya Kitoh

Publikováno v: ASME 2013 11th International Conference on Nanochannels, Microchannels, and Minichannels.

Several researches dealing with the single-phase forced convection heat transfer in micro tubes have been published in the past years. Most of their tests results are significantly departed from those of the traditional forced convection heat transfe

Three-Dimensional Flow Computations Around an Airfoil by Building-Cube Method

Autor: Yuta Sakurai, Kazuhiro Nakahashi, Matthias Meinke, Aya Kitoh

Publikováno v: 44th AIAA Aerospace Sciences Meeting and Exhibit.

In this paper, flow around the Aerospatiale A-airfoil with a small spanwise extent at Re=2.1x10 6 and 13.3-deg angle of attack is computed using the Building-Cube Method (BCM), that was proposed aimed for DNS around real geometries with an expectatio
