On the relative impact of subgrid-scale modelling and conjugate heat transfer in LES of hot jets in cross-flow over cold plates [PDF]

open access: yes, 2011
This work describes numerical simulations of a hot jet in cross-flow with applications to anti-ice systems of aircraft engine nacelles. Numerical results are compared with experimental measurements obtained at ONERA to evaluate the performances of LES in ...

Systematic Investigation on Conjugate Heat Transfer Rates of Film Cooling Configurations

open access: yesInternational Journal of Rotating Machinery, 2005
For the determination of the film-cooling heat transfer, the design of a turbine blade relies on the conventional determination of the adiabatic film-cooling effectiveness and heat transfer conditions for test configurations.

Conjugate heat transfer for turbulent flow in a thick walled plain pipe

open access: yesEPJ Web of Conferences, 2018
Laminar and turbulent flow have their own characteristics in respect of heat transfer in pipes. While conjugate heat transfer is a major concern for a thick walled pipe with laminar flow inside it, there are limited studies about a turbulent flow in a ...

Study of In-Cylinder Heat Transfer Boundary Conditions for Diesel Engines Under Variable Altitudes Based on the CHT Model

open access: yesFrontiers in Energy Research, 2022
The reliability of combustion chamber components is mainly determined by the thermal load of diesel engines. Under the plateau operation condition, diesel engine performance degradation and ablation area appear.

Flow and Temperature Fields in Cooling Devices with Embedded Serpentine Tubes [PDF]

open access: yes, 2014
The turbulent flow (Re = 5124) and conjugate heat transfer in heat-sink designs of the tube-on-plate type are numerically investigated. The cooling configurations employ a serpentine tube partially (or fully) embedded inside the plate.
