This paper reviews current capabilities for predicting flow in the cooling passages and
cavities of jet engines. Partly because of the need to enhance heat transfer coefficients …

Computations were performed to study the three-dimensional flow and heat transfer in a U-
shaped duct of square cross section under rotating and non-rotating conditions. The …

This paper reports results from the use of laser-Doppler anemometry (LDA) to measure the
mean and fluctuating flow field in a U-bend of strong curvature, Rc/D= 0.65, that is either …

A two-equation turbulence model with new terms for Coriolis and rotational buoyancy has
been used for prediction of heat transfer from the leading and trailing sides of a rotating …

The present study deals with the numerical prediction of turbulent flow and heat transfer in a
2: 1 aspect ratio rectangular duct with ribs on the two shorter sides. The ribs are of square …

In the present study, a two-pass internal cooling channel with engine-similar cross-sections
was investigated numerically. The channel featured a trapezoidal inlet pass, a sharp 180 …

Publisher Summary Compact heat exchangers (CHEs) are characterized by a large heat
transfer surface area per unit volume of the exchanger, resulting in reduced space, weight …

This study focuses on the computation of periodic flow and heat transfer through stationary
and rotating ducts of square cross-section, with rib-roughened walls. Square-sectioned ribs …

Results from large eddy simulations (LES) of fully developed flow in a 90 deg ribbed duct
are presented with rib pitch-to-height ratio P/e= 10 and a rib height-to-hydraulic-diameter …

Numerical predictions of three-dimensional turbulent flow and heat transfer are presented
for a rotating two-pass smooth rectangular channel with channel aspect ratio of 2: 1. The …
