Videos capture nanofiber behavior under water aerosol exposure. Since its outbreak, the COVID-19 virus has infected more than 220.9 million people worldwide and has claimed…
The results may help engineers develop a way to inject drugs without needles. Squirting a jet of water through a drop of liquid may sound…
Power source clusters near rocket engine fuel injectors could create combustion oscillations. Combustion engines can develop high-frequency oscillations, leading to structural damage to the engines…
A certain type of oil droplets changes shape when cooled and shrunk: from spherical through icosahedral to flat hexagonal. Two competing theories couldn’t fully explain…
Scientists at IST Austria show that little differences in behavior decide between success and complete failure of epidemic control. What has fluid physics to do…
Curbing coronavirus spread in enclosed spaces means better masks, adequate ventilation. With research increasingly showing the COVID-19 virus is transmissible via smaller droplets suspended in…
How can clothing of a close-range shooter remain free of bloodstains? In 2009, music producer Phil Spector was convicted for the 2003 murder of actress…
COVID-19 needs no introduction. Last year, the disease, which is caused by the virus SARS-CoV-2, reached every continent across the globe. By the end of…
Nobel laureate in physics Richard Feynman once described turbulence as “the most important unsolved problem of classical physics.” Understanding turbulence in classical fluids like water…
The results indicate masks and proper ventilation may be key to allowing more capacity in schools, businesses, and other indoor areas. A new study from…
An international research team, led by Monash University, has discovered for the first time the mystery behind the formation of ‘coffee rings’ by examining the…
Tiny fluorescent particles, laser light used to study water flowing through tire grooves. When a vehicle travels over a wet or flooded road, water builds…
Aerosol simulations show how airborne particles containing SARS-CoV-2 spread within a music classroom and how to use portable HEPA air purifiers to reduce their spread….
Airflow patterns around two people conversing in typical situations, such as hair salons, medical exam rooms, and long-term care facilities. COVID-19 can spread from asymptomatic…
More preventive measures, such as shielding underneath tables and improving air conditioner filtration efficiency, could reduce exposure to COVID-19 within air-conditioned restaurants. The detailed physical…
Editor’s note: Varghese Mathai is a physicist at the University of Massachusetts Amherst who studies the flow of fluids and gases. He conducted a study…
A computation shows air purifiers in elevators and other confined spaces can actually increase saliva droplet dispersal, spreading COVID-19. The positions of air inlets and…
Engineers make it possible to simulate complete ‘dance’ of colliding vortices at reduced computational time. In 2018, passengers onboard a flight to Australia experienced a…
