Heat losses in a trapezoidal cavity receiver of a linear Fresnel collector: A CFD approach

Autor: Sergio Alcalde-Morales, Loreto Valenzuela, J.J. Serrano-Aguilera

Publikováno v: Heliyon, Vol 9, Iss 8, Pp e18692- (2023)

This paper presents a thermal study of a cavity receiver designed for a Fresnel-type linear solar collector (LFC). The study utilizes a two-dimensional computational fluid dynamics (CFD) model implemented in ANSYS Fluent. The thermal behavior of air

Publikováno v: International Journal of Thermal Sciences. 43:383-401

Resume Un materiau destine a subir de fortes contraintes thermomecaniques peut etre protege d'une usure precoce par un revetement depose par voie electrolytique. Nous nous proposons dans cet article de caracteriser ce type de revetement par une metho

Publikováno v: Wear. 201:163-170

The improvement of a weapon system needs to be balanced between the power of the powder and the lifetime of the gun barrels. When a projectile is fired, different phenomena bring a large amount of heat into the tube. These physico-chemical, thermal a

Deformation of a γ/γ′ waspaloy after laser shock

Autor: M. Condat, B. Decamps, L. Hautefeuille-Beylat, J.J. Serra, T. Thomas, C. Bourda, T. Puig

Publikováno v: Materials Science and Engineering: A. 154:183-191

Oriented single crystals of waspaloy were exposed to laser shocks along the 〈001〉 axis at power densities of 3 and 9.5 × 10 9 W cm −2 . Prio to testing, the spatial distribution of the beam energy was measured. Computations were performed to d

High Speed Damage Under Transient Conditions

Autor: S. Serror, J.J. Serra, O. Lesquois, Ph. Kapsa

The ETC A high speed tribometer is a facility able to achieve tests involving sliding speeds up to 350 m/s and loads up to 5000 N. The moving part is a 360 mm diameter stainless steel cylinder and the slider is a 5 mm side parallelepiped pin. The tes

Parameter estimation for a biological system: Model and experimentations

Autor: B. Claudet, J.J. Serra, Laurent Autrique, C. Lormel

Publikováno v: Scopus-Elsevier

Temperature evolution and skin burn process in biological samples exposed to laser radiation are investigated in this communication. A one-dimensional multi-layered model is presented and transient temperature is numerically estimated using a finite
