The capacity of these particles to remain suspended in the air and to spread in the environment depends largely on the size and nature of the air flow generated by the expiration of air. As with other ...

Researchers conducted a numerical study on droplet dispersion using high fidelity air flow simulation. The scientists found a single 100-micrometer cough droplet under wind speed of 2 meters per ...

A Dutch research team has outlined a new method to assess the coefficient of performance of air-to-water heat pumps by considering ambient temperature and relative humidity. The model is based on the ...
