This talk will discuss research on particle engineering and synthesis using sprays and aerosols performed by the speaker. Past research encompasses studies on drying kinetics of a single droplet/wet particle, drying-induced stresses of wet particles and pharmaceutical granules, morphological evolution of a droplet into a particle, 2D and 3D multiscale, multiphase modeling of spray and pneumatic drying processes, and modeling of droplet-droplet and particle-particle collisions. Recently, a need for sprays with very fine droplets was recognized. To address this challenge, I developed a novel method for production of aerosols of submicron droplets. Thus, my current research focuses on basic fundamental and applied studies using the novel aerosolization method: fluid dynamics of atomization, aerosol synthesis of submicron/ nanoparticles at room and moderate temperatures, flame and hightemperature aerosol synthesis of crystalline nanomaterials, microfluidic device producing submicron droplets and particles, and coating of particles in fluidized beds using aerosols with submicron droplets.
Dr. Maksim Mezhericher is currently a researcher at the Department of Mechanical and Aerospace Engineering of Princeton University, jointly appointed between the Complex Fluids Group and the Advanced Combustion and Propulsion Lab. He received his Ph.D. in Mechanical Engineering from the Ben Gurion University, Israel. The Ph.D. thesis was devoted to a fundamental study of spray drying processes. During 2009-2011, Dr. Mezhericher was a post doc at the Ben Gurion University within the framework of a German- Israel Foundation project (joint study with Prof. Tsotsas’ group, chair of Thermal Process Engineering, Otto-von-Guericke University, Germany). In 2011-2016, he served as a Senior Lecturer (tenured) at the Department of Mechanical Engineering of Shamoon College of Engineering, Israel. The research interests of Dr. Mezhericher broadly include basic fundamental and applied research of particle engineering and synthesis for pharmaceutical, energy and energy storage, medical, biotechnological, agricultural, nuclear and food applications; atomization of liquids into submicron droplets; fluid mechanics and transport phenomena in gasbubble-droplet-particle flows, pulmonary and ocular drug delivery using aerosols; microfluidic devices for liquid atomization and particle engineering.
Faculty, students, and the general public are invited.
