RISTransient Performance Analysis of Centrifugal Left Ventricular Assist Devices Coupled With Windkessel Model: Large Eddy Simulations Study on Continuous and Pulsatile Flow Operation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Computational fluid dynamics (CFD) simulations are widely used to develop and analyze blood-contacting medical devices such as left ventricular assist devices (LVADs). This work presents an analysis of the transient behavior ...
Cold Gas Spraying Copper Metal on AlN Ceramics as an Alternative to Thick Direct Bond Copper Substrates for Power Electronics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study investigates the use of cold gas spraying (CGS) as a low-temperature additive manufacturing method to bond copper onto aluminum nitride (AlN) substrates for electronic packaging of high-power applications. While ...
Metallic Phase Change Material's Microstructural Stability Under Repetitive Melting/Solidification Cycles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Metallic phase change materials (mPCMs) have been demonstrated as potential passive cooling solution for pulse power applications. The possibility of integrating a metallic PCM directly on top of a heat source, reducing ...
