Understanding of dynamic and transient wind environment is crucial to evaluating the outdoor thermal comfort pedestrians. The thermophysiological responses human body depend on both interaction with climate internal thermoregulation. coupled simulation CFD thermoregulation model provides a pathway predict under non-uniform conditions where local effects may dominate comfort. In this work, we ex...

Scaling-up and -down of conventional ideal lab-scale catalytic reactors often introduces strong nonidealities in the flow field which may drastically affect the expected reactor performances and effectiveness. Computational fluid-dynamic (CFD) analysis is required to assess the extent of such nonidealities. In the case of reactive systems, and in particular in the case of heterogeneous catalyti...

In this work, we introduce the framework for visualization and interactivity for physics engines in realtime, for short VIPER. It is able to execute various physical simulations, visualize the simulation results in real-time and offer computational steering. Especially interesting in this context are simulations running on remotely accessible HPC clusters. As an example, we present a particulat...

Abstract In the present work, a 5-component gasoline surrogate chemical kinetic mechanism has been developed and validated. The first novelty of this is that recently advanced H2/O2/CO/C1 detailed sub-mechanism adopted for accurately predicting laminar flame speeds over wide range operating conditions C2-C3 used due to its potential benefits on accurate propagation simulation in order overcome ...

Interest in renewable, green, and sustainable energy has risen sharply in recent years. The use of marine turbines to extract kinetic energy from the tidal current is gaining popularity. CFD modeling is carried out to investigate the surrounding flow behavior and thus develop effective marine turbine systems. However, visualizing the simulation results remains a challenging task for engineers. ...

System identification is used to develop an accurate and computationally efficient discrete-time aerodynamic model of a three-dimensional, unsteady CFD solution. This aerodynamic model is then used in place of the unsteady CFD solution in a coupled aeroelastic analysis resulting in a substantial savings in computational time. The methodology has the advantage of producing an explicit mathematic...

This paper presents the design and fabrication of proximity coupled feed disk resonator coated with Multi Walled Carbon Nanotubes (MWCNTs) and Polypyrrole-Chitosan (PPy-CHI) layers as a napropamide sensor. Computer Simulation Technology (CST) microwave studio was used to obtain the best design of disk resonator and feed line position in 5 GHz resonant frequency. Also, MWCNTs - PPy-CHI layers we...

This paper examines the method to simulate heat balances on building and urban surfaces by combining the 3D CAD-based thermal environment simulator with 3D steady RANS CFD simulations. The simulation results of the distribution of convective heat transfer coefficient in an urban canyon model are compared with that of a wind tunnel experiment. The effects of building geometries, including verand...
