Introduction
My research interests are in the study of fundamental thermo-fluid mechanic phenomena and how their theoretical understanding can be leveraged to improve the efficiency and sustainability of industrial processes. In particular, I am interested in the experimental and theoretical study of multi-scale fluid interfaces.
My current research is on the deposition of complex fluid droplets, with applications in advanced surface coatings.

The breakup of droplets in a high-speed air stream is investigated experimentally and theoretically. This study is based on experiments conducted by exposing pendant droplets to a high-speed air jet, which allowed for imaging of the droplets at high temporal and spatial resolutions while maintaining a large field of view to capture the breakup proc...
The rim and bag dynamics in aerodynamic droplet breakup are investigated experimentally and theoretically. Three main modes contribute to the breakup sizes in aerodynamic droplet breakup: the rim node, the remaining rim and the bag breakup modes. However, existing models only consider one mode and are, therefore, unable to predict the size distribu...
The present work studies low viscosity twin-fluid atomization experimentally and analytically to characterize and predict the droplet size distribution of the spray. The study is based on experiments conducted using commercially available twin-fluid nozzles with water as the liquid. Shadowgraph images were used to visualize the near-nozzle flow whi...
The present work investigates the breakup mechanisms of rims formed in the late stages of low Weber number aerodynamic droplet breakup. High-speed shadowgraph videos of droplet breakup at side and end-on viewing angles are used to visualize and quantify the breakup of the rims. The rims formed in droplet breakup are known to fragment bimodally, wit...
The present work studies low-viscosity two-fluid atomization experimentally and analytically in order to characterize and predict the formation and breakup of ligaments in the spray. The study is based on experiments conducted using commercially available two-fluid nozzles with water as the liquid. Shadowgraph images were used to visualize and char...
Questions
Question (1)
Hi everyone,
I am looking for a theoretical relationship for the discharge speed and density of a compressible fluid through a non-ideal nozzle. The isentropic flow relations give the theoretical speed and density of the flow through an ideal nozzle, but what do we do in the real world when we correct the mass-flow rate by a discharge coefficient? Can we determine the 'real' discharge speed and density theoretically with the use of the discharge coefficient?
Thanks for your help, and make it a great day,
Isaac
