Hitachi Automotive Systems, LTD. discusses Particleworks

“Responding to the requirement to evaluate cooling performance, Particleworks had become one of the candidates for simulation. We had used FVM (Finite Volume Method) based grid method CFD software already, and we decided to choose the more effective one by comparing the time for pre-processing and calculation speed. Simulation of the piston oil jet shows …

CFD testing of HeartAssist® LVAD performance under realistic working conditions

VADs are increasingly used to mitigate the shortfall in donor organs for cardiopathic patients awaiting heart transplants annually by providing a bridge-to-transplant, or to stabilize patients with congestive heart failure. While rotary VADs have smaller dimensions and simpler structures than pulsatile VADs, their continuous, high-speed, rotating blood-flow patterns represent a potential risk factor to patients …

EnginSoft and the European Space Agency investigate hydroponic plant growth for future space missions

EnginSoft has been collaborating with the European Space Agency (ESA) for the past ten years, working actively in the MELiSSA program. At present, this project’s main efforts concern the life support system sector and the idea of creating an artificially closed ecosystem that generates food and oxygen for space crews on longterm missions. The current …

Flow field optimization of a medical device

CAE is highly effective for product optimization. In this technical article, we describe how a hybrid method of computational fluid dynamics analysis was used to enhance the design of a medical device to improve its ability to maintain a stable microclimate around a patient, but also to reduce both the computational efforts and the time …

Design and Analysis of Chain Drives made easy by RecurDyn Multi-Body Software

Chain models are among the largest and most complex that can be simulated with multi-body technology. First, depending on the chain length, the number of moving bodies could become remarkable. Second, contacts disturb the solution all over the chain, causing continuous impulsive excitation of the mechanism. Third, chain links are bodies with reduced inertia, whose …

Intermarine Shipyard tests Flownex SE for its naval piping systems

There are various piping systems that convey many different fluids on board a vessel. Each fluid must reach its user at the right pressure and flow conditions. Accessories such as valves, bends, fittings and pipes induce pressure losses (as a result of factors such as pressure (p), flow rate (q) and pipe size (diameter, A)). …
