Computational Modelling is a resource hungry discipline requiring extensive expertise and large amounts of time. The ISO-STEP (International Standards Organisation Standard for the Exchange of Product Model data) is proposing an integrated product model for CFD applications. This paper presents a specification for a STEP compliant building product model for CFD analysis incorporating IBM’s Open...

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...

Stability against capsizing is one of the most fundamental requirements to design a ship. In this research, for the first time, CFD is performed to predict main modes of capsizing. CFD first is conducted to predict parametric rolling for a naval ship. Then CFD study of parametric rolling is extended for prediction of broaching both by using CFD as input to NDA model of broaching in replacement ...

Recent advances in computational fluid dynamics (CFD) codes along with high performance computing hardware made the codes more useful in many engineering applications. For instance, single-phase CFD codes have long been used to predict the fluid flow in fuel channels of a pressurized water reactor (PWR) [1, 2]. Considering the current affordable number of computation mesh is a little below one ...

In the framework of the ASCHLIM project, a group of European experts in thermal hydraulic calculation has been clustered to evaluate the state of the art of CFD (Computational Fluid Dynamics) codes applied to ADS designs. The work of this group, supported by the Vth Framework Program of the European Union, has been focused on CFD analysis of the experiments that includes thermal hydraulic pheno...

Gastric cancer (GC) is the fourth most common cancer and the second major cause of cancer-related deaths worldwide. In our previous study, a novel and sensitive method for quantifying cell-free DNA (CFD) in human blood was established and tested for its ability to predict patients with tumor. We want to investigate CFD expression in the sera of GC patients in an attempt to explore the clinical ...

Flow of a blood analog is modeled through a patient-specific aortic coarctation using ANSYS Fluent software. Details of the patient data (aortic geometry and prescribed flow conditions) were provided by the MICCAI-STACOM CFD Challenge website. The objective is to predict a blood pressure difference across the rigid coarctation under both rest and exercise (stress) conditions. The supplied STL g...

The study presents two novel approaches for gust response analysis of elastic free aircraft configuration using computational fluid dynamics (CFD) tools. The direct approach involves full aeroelastic dynamic simulation within a CFD run. The hybrid approach involves computing rigid sharp-edge gust responses in a CFD run, evaluating the gust input forces due to arbitrary gust profiles via convolu...

In this paper, the heat pipe heat exchanger (HPHE) is considered and computational fluid dynamics (CFD) is used to analyze its evaporator’s performance and based on it, will be try to increase the thermal efficiency and to optimize the distribution of fluid flow in this type of heat exchangers. The CFD principles which are made use in this article are effective and appropriate methods that usin...

In this study we used computational fluid dynamics (CFD) to analyse the therapeutic effect of an oral device (mandibular advancement splint – MAS) that protrudes the lower jaw during sleep on obstructive sleep apnea (OSA). Clinical data of 4 patients were used for CFD analysis, with patient selection being on the basis of their known different treatment responses. Anatomically accurate upper ai...
