Fundamentals of Gas-Solid Flows: Application to Transmission of Respiratory Diseases

SyracuseCoE is pleased to host Dr. Goodarz Ahmadi as the speaker for our May Research and Technology Forum. Professor Ahmadi’s presentation will cover topics including:

• Mechanics of gas-solid two-phase flows, including particle transport, deposition, and dispersion in turbulent flows
• Advances in airflow simulations using the Reynolds Averaged Navier-Stokes (RANS), Large-Eddy Simulations, and Direct Numerical Simulations (DNS)
• Lagrangian particle trajectory analysis method and diffusion model approach
• Examples of computational modeling of gas-solid flows in environmental and biological applications
• Transport and deposition in duct flows, including model verification and accuracy testing
• Pollutant transport and deposition in indoor and outdoor environments, including in respiratory passages

Ahmadi will close his presentation with examples of dispersion and transport of airborne respiratory droplets in indoor environments, such as offices and classrooms, in connection with the transmission of respiratory viruses, including SARS-CoV-2.
