For several decades, turboexpander designers have relied on experience and traditional design tools to create their products. Recent advances in CFD (computational fluid dynamics) software and desktop computing power have made it possible for some manufacturers to investigate unique fluid flow fields in routine design applications. In this paper, four case studies of CFD in high performance exp...

This paper discusses the development of a computational approach for accurately determining static and dynamic stability and control characteristics of USAF high-performance fighter aircraft. A graduated approach is used to incrementally add Computational Fluid Dynamics (CFD) simulation capability using DoD HPC resources. Static simulations, prescribed motion flight test maneuvers, and System I...

Combining the computational fluid dynamics (CFD) and the design of experiments (DOE) methods, as a mixed approach in modeling was proposed so that to simultaneously benefit from the advantages of both modeling methods. The presented method was validated using a coal hydraulic classifier in an industrial scale. Effects of operating parameters including feed flow rate, solid content and baffle le...

Transportation of unrefined crude oil from the production unit to a refinery or large storage area by a pipeline is difficult due to the different properties of crude in various areas. Thus, the design of a crude oil pipeline is a very complex and time consuming process, when considering all the various parameters. There were three very important parameters that play a significant role in the t...

Computational Fluid Dynamics (CFD) simulations are aimed to reconstruct the reality of fluid motion and behaviour as accurately as possible, to better understand the natural phenomena under specified conditions. Ideally, computational models would need to cover different scales and geometric configurations, and the classic CFD solvers most often require long computational times to satisfy the c...

In this chapter, the development, implementation and evaluation of a suitable curriculum for students to use computational fluid dynamics (CFD) as part of a fluid mechanics course at intermediate undergraduate level are described. CFD is the simulation of fluids, heat transfer, etc., using modelling, that is, mathematical physical problem formulation, and numerical methods which includes, discr...

Computational fluid dynamics (CFD) is a simulation tool, which uses powerful computer and applied mathematics to model fluid flow situations for the prediction of heat, mass and momentum transfer and optimal design in industrial processes. It is only in recent years that CFD has been applied in the food processing industry. This paper reviews the application of CFD in food processing industries...

This work couples a computational fluid dynamics (CFD) code and rotorcraft computational structural dynamics (CSD) code to calculate helicopter rotor airloads across a range of flight conditions. An iterative loose (weak) coupling methodology is used to couple the CFD and CSD codes on a per revolution, periodic basis. The CFD uses a high fidelity, Navier-Stokes, overset grid methodology with fi...
