Curriculum Vitae
ESR9 - Small-scale turbulence and spatial distribution of droplets in clouds
Objectives

The project is aimed at joint investigation of droplet spatial distribution and small-scale turbulence in clouds. We plan to measure positions and velocities of cloud droplets in a two-dimensional plane enlightened by a laser sheet technique. We will build a device allowing for uniform illumination of cloud volume of the area ~50x50 cm2 and of variable thickness (~1mm to ~2cm). This will allow for visualization of cloud droplets within this volume and quantitative multi-scale (from below Kolmogorov scale to Taylor micro-scale) measurements of droplet clustering and small scale turbulence. We will test a prototype of this instrument in a laboratory cloud chamber at UW and in wind tunnels at MPG. We will use the instrument to measure properties of clouds in a mountain laboratory (preferably Schneefernenhaus at Zugspitze).

Expected Results

Quantitative information about droplet spatial distribution and small-scale turbulent mixing in clouds disseminated in scientific publications, increased experience in development of new sensors.

Planned secondment(s)
  • MPG (Goettingen)        Month 15-17: experiments in the wind tunnel of MPG
Comments

I received both my Bachelor and Master degrees in Mechanical Engineering from Iran University of Science & Technology (IUST). During my Master studies, I attended “Combustion & Fuel Lab” of IUST as a Research assistant. There, we tried to study dust particle clouds combustion process from heat & mass transfer point of view by using theoretical approaches for thermal modelling of solid fuels combustion.

Since Feb 2017, I have started my PhD under the framework of “COMPLETE” project in Poland at University of Warsaw, Institute of Geophysics. I am conducting research on "Small-scale turbulence and spatial distribution of droplets in clouds" which would be mostly done by experimental approach.
