Pipelines are often subject to leakage due to ageing, corrosion, and weld defects, and it is difficult to avoid as the sources of leakages are diverse. Several studies have demonstrated the applicability of the machine learning model for the timely p...

In this study, simulations are carried out using the Euler-Euler granular model in STAR-CCM+ for a gas-solid flow in a rectangular bubbling fluidized bed. The problem studied was announced as Small Scale Challenge Problem (SSCP-I) in 2013. Experiment... Read More about Simulation of rectangular fluidised bed with Geldart D particles..

Numerical investigation of the effect of bed height and coefficient of restitution on the minimum fluidization velocity of a cylindrical fluidized bed.
Presentation / Conference Contribution
KARNIK, A., RANGARAJAN, A. and TANDON, A. 2013. Numerical investigation of the effect of bed height and coefficient of restitution on the minimum fluidization velocity of a cylindrical fluidized bed. Presented at the 8th International conference on multiphase flow (ICMF 2013), 26-31 May 2013, Jeju, Korea.

Numerical simulation for 4 different ratios of initial bed heights (H) to base diameter (D), were performed; viz. 0.5, 1, 2 and 3. Glass beads of density 2600kg/m3 and with an average diameter of 550μm were used for all the simulations. Simulations w...

Available from: https://www.ilasseurope.org/ICLASS/ILASS2008_COMO/file/papers/5-1.pdf

The effect of electric charge, residing on particles, upon the phenomenon of preferential accumulation is investigated using direct numerical simulations of forced isotropic turbulence. It is well known that particles with a certain range of Stokes n... Read More about Destruction of preferential accumulation using Lorentz force interactions..

An Eulerian–Eulerian formulation for erosion modelling: an alternate approach.
Presentation / Conference Contribution
TANDON, M.P., MOHAN, S.J., KARNIK, A.U. and GADA, V.H. 2018. An Eulerian–Eulerian formulation for erosion modelling: an alternate approach. Presented at the 7th International and 45th National fluid mechanics and fluid power conference (FMFP 2018), 10-12 December 2018, Mumbai, India.

Sand is commonly produced besides petroleum fluids and it presents a major erosional hazard leading to pipe failures. Particle erosion is a complex process in which material is removed due to the repeated particle impacts. Conventionally, a CFD flow...
