Technical Program Highlights

Abstract

In this presentation, a context that defines and addresses the needs of advanced algorithms, analytics, and simulation for the industry in a forward-looking sense will be presented. As such, community of researchers in Computational Fluid Dynamics (CFD) is significantly committed to High Performance Computing (HPC) to secure more in-depth understanding of some of the world’s challenging phenomena. In academia, that spans across many sub-disciplines. But, abundance of problems / issues / design ideas of next generation products is now, perhaps for the first-time meeting abundance of data from the real world.  At the same time, cross-discipline smart algorithms are leading to disruptive possibilities of gaining insight faster than traditional (HPC-) CFD approaches. Given that life cycle value of any expensive industrial equipment is typically 5X+, data is driving significant insight for design, performance and life optimization. CFD is catching up. In many forms, it is extending its reach to value, with speed, ease and capacity. A perspective of that landscape referring to different industry segments and how they are defining future of CFD and analysis at large.

Abstract

Atmospheric convections such as dust devils, dust storms, thunderstorms, mesoscale convective systems, tropical cyclones, etc. are the type of nature convections which have multiscale evolution. The spatial scale of evolution of these systems ranges from the few meters to few hundreds of kilometers and temporal scale from few hours to a week. In case of atmospheric moist convection, the evolution of single cloud system with spatial scale range within few kilometers may affect the evolution of an ensemble of cloud system having a dimension of few thousand kilometers. Generally, in the numerical modeling of such evolutions, the spectrum of scales resolved into artificially separated scales in which local effects associated with resolved scales are simulated and unresolved scale processes are represented as statistically equilibrium parameterizations. However, the accurate simulation and prediction of their behavior are essential to avoid socio-economic consequences associated with them. The talk will discuss computational fluid dynamics of multiscale evolution of tropical cyclones over Bay of Bengal and occurrence of thunderstorms over South India. It will also present the requirements regarding development of CFD techniques and High-Performance Computing for better simulation of such multiscale evolutions.

Abstract

Though electrification is being speculated to be the future of Automobiles, research in conventional powertrain continues to be of importance. The need for CO2 emission reduction and fuel economy has brought the downsizing of engine to limelight among Automotive OEMs. Hence, digital product development is being intensified to evaluate more conceptual designs for better performance and in less time. The improved performance of airflow and combustion, thermal management, lubrication and exhaust after treatment systems is inevitable while downsizing the engine. Traditionally, at the system level, one-dimensional approach is used considering faster solutions, but compromising on the interactions between components. On the other hand, 3D-CFD simulations which place a higher load on the time factor, is used for performance analysis at the component level. The lubrication system of automotive powertrain poses interesting challenges in developing efficient pumps, valves, bearings, piston jets, filters, coolers to perform at different speed and load conditions. Complex issues such as pump cavitation, bearing damage, engine oil warm up, are predicted and minimized at the development stage with 3D-CFD simulations. This involves solving transient, multiphase flows with heat transfer on moving and deforming meshes in multiple components of the system. Therefore, efforts are towards developing a CFD code with superior meshing strategy, robust numerical algorithms and solver accuracy with faster solution time. High performance computing plays a vital role in realizing the objectives of simulation driven product development.

Abstract 

Computational Fluid Dynamics has become an indispensable tool for design and development of technologies related to heat and fluid flow. Analysis of practical configurations which involve mostly turbulent flows, require massive computational power. This is achieved by aggregating computing power, a practice commonly known as High Performance Computing (HPC). The talk will present a short overview on HPC, its application to CFD and showcase few state of the art simulations.
