Coupled Vibro-Acoustic and CFD Modeling Solution for Complex-Shaped Mufflers Subject

Flow within a duct strongly affects the propagation of acoustic waves. This effect must be addressed by the vibroacoustic modeling of duct systems that are subject to flow. The effective sound propagation speed in a…

Electric Steelmaking Coupled Multiphysics Simulation by Finite Elements

State of the art computer aided coupled multiphysics simulation tools can be advantageous in the understanding and design of industrial processes. This paper presents such a tool for electric steelmaking, metallurgical…

Alternative Solution Algorithms For Primal And Adjoint Incompressible Navier-Stokes

Regardless of the specific discretisation framework, the discrete incompressible Navier-Stokes equations present themselves in the form of a non-linear, saddle-point Oseentype system. Traditional CFD codes typically…

Using CFD flow fields to inform acoustic finite element models of complex mufflers with thermal and flow effects

Many actual muffler systems with complex geometry have large temperature variations and large variations in the flow field under normal operating conditions. Often perforated regions and other complex design elements…

A Mixed Hybrid Finite Volume Scheme For Incompressible Navier-Stokes

Mixed Virtual Elements (MVE) is an innovative class of discretization schemes allowing solution of PDEs on virtually any mesh; such schemes stem from the idea of building discrete operators mimicking certain key…

Integrating Design Portal System

As part of the effort to create the new aero space craft, China Aerospace Science and Technology Corporation (CASC) analysed and optimized their design processes. The INTEGRATING DESIGN PORTAL SYSTEM (IDPS) helps to…

Aero Forming - An Introduction of Collaborative Engineering

The decrease of physical prototypes and the growing power of simulation in the design process require greater control in the design chain calculation. This is the main reason for the arrival of SDM in the perimeter of…

Development of system identification technique for the control of structually flexible SMT machines

Acquiring dynamic characteristics of a system is an important issue for predicting and evaluating the system’s performance in early development stages in order to shorten the development time as well as to meet required…

Enhancements and validation of FPM fluid structure interaction module applied to curtain airbag deployment

Models to represent in position situations based upon uniform pressure assumptions are well established and have been used extensively in the automotive industry for more than 15 years. More recently, in the beginning…

Conjugate heat transfer in hypersonic flows

In certain applications, different regions of the computational domain experience flow conditions/physics that are so different that it is very difficult for a single solver to produce sufficiently accurate results…
