Comparative numerical study on pressure drop in helically coiled and longitudinally C-shaped pipes

Autor: Elwardi Bitam, Lyes Bordja, Yassine Demagh

Publikováno v: SN Applied Sciences. 2

In the present work, the shear stress transport (SST) $$k - \omega$$ model is used to simulate internal turbulent flows in curved tubular heat exchangers and the resulting friction factors $$C_{f}$$ are calculated. A helically coiled configuration wa

1D and 2D Numerical Validation of Lee's Evaporation Model with OpenFOAM

Autor: Yassine Demagh, Alladdine Achi

Publikováno v: 2019 8th International Conference on Modeling Simulation and Applied Optimization (ICMSAO).

In the present study 1D Stefan evaporation and 2D film boiling problems will be studied numerically using the volume of fluid (VOF) method under OpenFOAM 2.4.0 CFD package. The mass transfer across the interface vapour/liquid is determined using the

A 1D thermal model for PTR including pressure drop and kinetic energy change within the fluid: Conventional absorber tube vs. S-curved

Autor: Yassine Demagh, Lyes Bordja

Publikováno v: SOLARPACES 2018: International Conference on Concentrating Solar Power and Chemical Energy Systems.

New receiver designs have been proposed to boost the heat transfer rate in the parabolic trough receiver (PTR) absorber tube, which can further improve the overall performances of the parabolic trough module. The objective of this study is to investi

A design method of an S-curved parabolic trough collector absorber with a three-dimensional heat flux density distribution

Autor: Hocine Benmoussa, Yassine Kabar, Ilyes Bordja, Yassine Demagh

Publikováno v: Solar Energy. 122:873-884

This paper presents the first study on the feasibility of an S-curved/sinusoidal absorber for a use in parabolic trough collectors (PTCs). The conventional straight absorber located along the focal line of the PTC is replaced by an S-curved/sinusoida

Surface particle motions in rotating cylinders: Validation and similarity for an industrial scale kiln

Autor: Mohammed Lachi, Samira Noui, Yassine Demagh, Lyes Bordja, Hocine Ben Moussa

Publikováno v: Powder Technology. 224:260-272

Dissimilarities are likely to exist between experimental rotating cylinders and commercial scale rotating drums like cement kilns. Consequently, it is quite difficult to draw conclusions from these experiments and apply them directly to industrial co
