The powering requirement of a land yacht is one of the most important aspects of its design. In this respect the wind tunnel testing is an effective design tool. In fact, changing the parameters of the vehicle and testing the changes in the wind tunnel will give us a better understanding of the most efficient vehicle, and yet it is time consuming, expensive, and has inherent scaling errors. Ano...

We are currently developing new numerical simulation methods and computational fluid dynamics (CFD) codes designed for advanced fluid-structure interaction (FSI) applications that have moving mechanical components and/or changing domain shapes. The method is called Dynamic-Mesh (DM) and is currently being implemented in parallel within our XFlow CFD simulation code. This method involves the tig...

Rendering realistic moving water is one of the key techniques that immerse the viewers into interactive graphics world including computer games. Physical simulations based on computational fluid dynamics (CFD) is useful for rendering the realistic behaviour of water. However, real-time fluid rendering has been one of the challenging tasks because of high computational cost of CFD. According to ...

The current computational fluid dynamics modeling technique is capable of identifying the optimal reagent injector locations for SNCR systems. However, this technique cannot quantify NOx reduction and ammonia slip. ABB carried out a research project to investigate various computational fluid dynamics (CFD) models and the chemical kinetics of nitrogen species during coal combustion. An enhanced ...

Despite the many advantages, ejector refrigeration systems have not been able to penetrate market because of two prevailing reasons: low coefficient performance and relevant influence operation on whole system. Indeed, depends local flow phenomena occurring within ejector. Thus, improving relies understanding fluid dynamic at "component-scale" integrating such information "system-scale". This p...

Computational Fluid Dynamics (CFD) is a computer-based tool for simulating fluid movement. The main advantages of CFD over other fluid mechanics studies include: substantial savings in time and cost, the analysis of systems or conditions that are very difficult to simulate experimentally (as is the case of the airways), and a practically unlimited level of detail. We used the Ansys-Fluent CFD p...

This paper gave an overview of the past and present applications of various Computational Fluid Dynamics (CFD) methods for indoor environment modeling. Typical applications used the CFD to calculate airflow, air temperature, contaminant concentrations, and turbulence in enclosed environment for studying or designing thermal comfort and indoor air quality. With simple airflow and geometry, the C...

Computational fluid dynamic (CFD) models are ubiquitous in aerodynamic design. Variable-fidelity optimization algorithms have proven to be computationally efficient and therefore suitable to reduce high CPU-cost related to the design process solely based on accurate CFD models. A convenient way of constructing the variable-fidelity models is by using the high-fidelity solver, but with a varying...
