Modelling rare or extreme events is critical in many domains, including financial risk, computer security breach, network outage, corrosion and fouling, manufacturing quality and environmental extremes such as floods, snowfalls, heat-waves, seismic hazards and meteorological-oceanographic events like extra-tropical storms, hurricanes and typhoons. Statistical modelling enables us to understand extremes...
Summary form only given, as follows. The complete presentation was not made available for publication as part of the conference proceedings. Computational Fluid Dynamics (CFD) is one of the active and highly demanding research areas, and in which computers with the application of numerical methods are used to solve problems involving fluid flows. With the recent advances in the field of CFD, numerical...
Gas-liquid systems form a key component of many chemical industry processes. In such systems, the knowledge of the gas volume fraction, its distribution and its eventual effect on mass transfer and reactions is absolutely essential. Experimental measurements have allowed to look into such systems to a good level of details, resulting in numerous correlations, which are commonly used in the design...
Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
The recent emergence of ubiquitous smart communication devices accelerate people to post the current trending topics in real time as micro blogs, tweets, posts and multimedia content on social media sites along with geographical location tags (geo-tags). Specifically, during recent floods in Tamilnadu 2015, the early warnings about flooded areas emerged to get posted in popular social media with geo-parsed...
Parallel finite element algorithms based on object-oriented concepts are presented. Moreover, the design and implementation of a data structure proposed are utilized in realizing a parallel geometric multigrid method. The ParFEMapper and the ParFECommunicator are the key components of the data structure in the proposed parallel scheme. These classes are constructed based on the type of finite elements...
As microblogs such as Twitter become commonplace, greater importance needs to be given to data generated in those media as sources for information mining. This paper proposes a computationally simple model for future outcome prediction at current time using shot-term data generated from microblogs (tweets in particular). The model adopts an asset price bubble model, which is non-probabilistic. A threshold...
This work presents the results from a round robin study of molecular simulation programs. Widely used molecular codes including GROMACS, LAMMPS, NAMD, TINKER, DL_POLY, Towhee, and ms2 were applied to a set of simple molecular simulation tasks by independently acting experienced users. The basic question was: "If different people try to do the same thing with different programs, will they get...
Progress in utilizing high performance computing (HPC) establishes molecular dynamics (MD) as an appropriate tool to give further insight into the nature of evaporation dynamics.
The human skin is the largest organ in the body which interacts with the environment and protects the body from excessive water loss, attacks by pathogens or abrasion from outside. Both cosmetic and pharma industries quite often have contrasting needs, that is, cosmetic industry desires that the lotion/prescription applied should not penetrate through the skin, whereas, in pharmaceutical industry...
For heterogeneous dynamic short-range molecular dynamics simulations it is critical to employ suitable load-balancing methods to minimize the time to solution. However, designing and parametrizing the optimal load-balancing method is a complex task, depending on detailed properties of the simulation scenario.The main challenge in balancing the load of molecular dynamics simulations is the extreme...
Molecular dynamics simulation is a powerful tool for the investigation of nanoscopic processes that are hard or impossible to investigate by experiment in detail at the molecular level. The present work concerns tribological properties of model systems which are described by the Lennard-Jones truncatedshifted potential. Two related scenarios are studied: 1) Couette flow; 2) lubricated contact of two...
This paper presents numerical methodologies for the robust, accurate and faster solution of the steady state free surface flows. Numerical solution of free surface flow problems using pressure based coupled solver is emerging trend in CFD community that allows implicit coupling of pressure, velocity and volume fractions and provides quiet robust and faster solution. Due to strong presence of body...
Numerous latest high power electronic circuit systems use an external cooling channel filled with circulating liquid coolant which acts as a heat sink to remove generated heat from surrounding components. While filling the coolant, air in the channel has to be completely removed before the final sealing is applied for good thermal and Noise, Vibration & Harshness (NVH) performance of the heat...
