Under different types of internal and external faults transformers, electrical quantities such as voltage, differential current transformer oil flow rate change accordingly. In this paper, the variation law is studied, other under abnormal conditions inside outside area verified by simulation. The characteristics are different, judged. At same time, ANSYS Maxwell 3D, Fluent software used to mod...

The subject of this research is the development a digital twin for process mixing components gas mixture in mixer generator. problem motivated by concept digitalizing modern production and considered relation to technology question generating given composition homogeneity. A gas-dynamic model an unsteady flow has been constructed numerical study carried out using Ansys Fluent software. Reduced ...

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...

Abstract—Heat transfer due to forced convection of copper water based nanofluid has been predicted by Artificial Neural network (ANN). The present nanofluid is formed by mixing copper nanoparticles in water and the volume fractions are considered here are 0% to 15% and the Reynolds number are kept constant at 100. The back propagation algorithm is used to train the network. The present ANN is t...

Particle erosion from slurry flow is a common problem in many industrial applications, including the mining and the oil and gas industry. Erosion modelling is a known complex problem, and consists of three equally important parts; fluid flow modelling, particulate flow modelling, and erosion modelling. It is the first of these, the fluid flow, which is analysed here. The paper compares three di...

The aim of the present paper is to analyze several port configurations in the FairbanksMorse 38D8-1/8 marine diesel engine. The motivation comes from the high number of intake and exhaust ports which characterizes this engine. The scavenging and trapping efficiency were studied by modifying several parameters related to the ports, such as the inclination, shape, pressure and number. To this end...
