Background and activities

Career Summary:

I am currently working as a postdoctoral research fellow at NTNU with the collaboration of SINTEF Energy AS Company in DiHl-Tech project. This particular position will involve doing experiments in a cold-flow (non-reacting) analogue of the burner. The plan is to use a canonical turbulent channel flow. The objective is to enhance the mixing of the fuel surrogate (helium) away from the channel wall to create a homogeneous distribution of fuel in the shortest distance from the injection. The plan is to try to do this by altering the free-stream turbulence with an active grid. This will help to understand how we could reduce the emission of CO2 to the world. I have also worked as an academic researcher in the Mechanical Engineering Department at the University of Newcastle, Callaghan, NSW, Australia from June 2012 to February 2019. In all my research career life, my interested areas of investigating classical grid turbulence, boundary layer, side-by-side composite grid turbulence (shear and shear-less mixing layer), and wake flow. Additionally, I have also eight months of teaching experience as an Assistant Professor in Mathematics discipline at American International University Bangladesh. Furthermore, I am also working as a casual academic in Mathematics and Mechanical Engineering Discipline since 2017 at The University of Newcastle. Moreover, I have received much international training from organizations such as University teaching certificate from UoN and Project management from AIUB. All these are dreaming me to do much better and now my vision is to work in engineering and industry professionals.

Research Experiences:
  • Grid turbulence: Grid turbulence measurements were carried out at low Reynolds numbers to investigate low of the small-scale turbulence (decay exponent, energy dissipation, skewness, flatness and scale-by- scale energy budget). We used grid turbulence because it is close to homogeneous isotropic turbulence. In recent time, our research team found that grid with different mesh sizes and solidity could use in the mining industry and protect the coal stacks form the mixture of dust. This innovation definitely will help to make huge amount of benefits to the mining industry to producing pure coal and ultimately Australian revenue will be boosted up.
  • Interaction flows: Interaction between two grid turbulent flows with and without mean shear with different length scales was studied. In this study, flows were generated using two different composite grids, which made of side-by-side grids that produce different homogeneous and isotropic turbulence flows. These kinds of flows are often found when the flows over the upper and lower surfaces of an aircraft interact with each other.
  • Rough wall turbulent boundary layer: The effect of 2D roughness on a turbulent boundary layer also investigated. We studied here, the contribution of form drag (generated by the roughness) to the total drag. We also studied how the scale-by-scale energy budget in a boundary layer is affected due to surface roughness. These studies are also important in understanding certain phenomenon observed in the environment and in the chemical industry.
  • Numerical Simulation: Numerical (Spectral Method and Large Eddy simulation) studies are carried out of a fluid passing through a rectangular straight duct in the presence of the magnetic field and turbulent flow.
