Occurrence of laminar separation bubbles on solid walls of an elliptic cylinder has been simulated using a recently developed transitional model for boundary layer flows. Computational method is based on the solution of the Reynolds averaged Navier-Stokes (RANS) equations and the eddy-viscosity concept. Transitional model tries to simulate streamwise fluctuations, induced by freestream turbulen...

Semantic Web technologies will deeply influence the further development of the Internet Economy. A major challenge is, however, to find a practical solution for trust problems arising from their deployment in real-world scenarios. In this paper we develop a concrete application scenario based on Semantic Web technologies for the domain of business to consumer electronic commerce to illustrate t...

In todays tech-driven world, digital wallets such as Paytm, GPay, MobiKwik, and so on, are gaining immense popularity among consumers. With economies becoming more consumers opt for computerized alternatives to the traditional leather wallet, industry has become a profitable base potential investors. India, specifically, growth of been propelled by demonetization policy, which significantly red...

To simulate the effect of free st ream turbulence on turbulent spot formation, experiments were conducted on the interaction of localized three-dimensional disturbances with the harmonic waves in a laminar boundary layer on a flat plate. Experiments conducted in three-dimensional diverging flow (but zero pressure gradient) show, while individually the disturbances decay downstream, their intera...
