Multiphase Fluid-Dynamics
This research topic includes fluid dynamic studies of adiabatic two-phase and three-phase flows aimed at improving accuracy of pressure drop models for oil & gas transportation (gas-liquid, liquid-liquid, and gas-liquid-liquid flows) and efficiency of gas cleaners equipments (gas-solid and gas-liquid-solid flows). Phase distribution and flow regime transitions are also deeply investigated.
Drop analysis
Analyses of drop-surface interaction and evaporative dropwise cooling for both sessile and impinging drops.
The interactions between drops and solid surfaces or gas/liquid interfaces are analyzed from a thermal and mechanical standpoint, evaluating equilibrium configurations after drop deposition or impacts.
As for solid surfaces, experimental analyses are conducted to evaluate the drop geometric characteristics (shape, contact angle) and thermal parameters during evaporation (times, power, fluxes).
As for gas/liquid interfaces, Computational Fluid Dynamics (CFD) studies are carried on to characterize the evolution of the crater and crown caused by the drop impact.
Wettability analyses, studies of surface covering capability of drops or sprays and heat transfer analysis are applicable to improve printing processes, electronic devices cooling or spray treatment of agricultural fields.
Refrigerant fluids
This field of study analyzes heat transfer and fluid dynamic characteristics during flow boiling and convective condensation of new refrigerants inside both standard and specially configured tubes (microfin tubes, herringbone tubes, multiport mini-channels).
