The fluid-structure interaction simulation of shockand detonation-loaded thin-walled structures requires numerical methods that can cope with large deformations as well as local topology changes. We present a robust level-set-based approach that integrates a Lagrangian thin-shell finite element solver with fracture and fragmentation capabilities and an Eulerian Cartesian fluid solver with optio...

This paper experimentally studies the heat absorption performance of a heat sink with vertical embedded heat pipes in the aluminum blade. The cooling system with embedded heat pipes distributes heat from the CPU to both the base plate and the heat pipes, and then transfer heat from fins to the Environment. The thermal resistance and heat transfer coefficient are evaluated for natural convection...

2A12 aluminum alloy is a high-strength aerospace alloy. During its extrusion process, the process parameters have great impact on microstructure evolution of extruded products. There are three controlled in actual project, which initial temperature billet, die and speed. Combined with back propagation (BP) neural network finite element method (FEM) simulation, based constitutive equation recrys...

In this work, the characteristics of flow and heat transfer of a fluid containing nano particles of aluminum oxide with the water volume fraction (0.1-0.2-0.3)(V/V) percent of the reports. The overall heat transfer coefficient, heat transfer and the average heat transfer fluid containing nano water - aluminum oxide in a horizontal double pipe counter flow heat exchanger under turbulent flow con...

In this study, a nickel cladding layer with bionic convex strip structure was applied to the surface of an aluminum alloy drill pipe, and laser technology used improve wear resistance pipe. Firstly, by observing morphological characteristics shell surface, ratio width strips spacing between obtained as 0.39–0.53, thus model constructed. Numerical simulations were performed, results showed that ...

Aluminum pipe is one of the most widely used materials for indoor and outdoor furniture because its durable characteristics low price. In general, with aluminum material not detachable connection method permanent, namely by welding process. This design aims to a multi-case joinery that can be types I, L, T, X, XYZ, which unplugged various furniture. The qualitative conducting literature studies...
