Ventilation, air filtration and disinfection have been found to be the main engineering measures to control the airborne respiratory infection transmission in shared indoor spaces. Wells-Riley model modifications allow to calculate the infection risk probability, but gaps in viral load data, risk control methods and dealing with incomplete mixing have resulted in ventilation recommendations falling ...

Heat exchangers (HEs) are often modeled using pinch point temperature difference (ΔT_pinch) methods when optimizing systems with HEs. However, even small inaccuracies in model predictions of HEs will introduce numerical noise that can cause optimization algorithms to fail. A recent study of single HEs suggests that highorder interpolation methods can compute ΔT_pinch much faster ...

The 400 million tons of waste plastic are disposed of around the world. A study reported by SINTEF estimates that the Norwegian fishing fleet dumps around 380 tons of plastic material in the ocean each year. This waste is increasing at an alarming rate, threatening aquatic life, polluting the environment, and causing serious diseases. Since this waste includes hydrocarbons and is a massive source ...

The International Journal of Multiphysics publishes peer-reviewed original research articles, review papers and communications in the broadly defined field of Multiphysics. The emphasis of this journal is on the theoretical development, numerical modelling and experimental investigations that underpin Multiphysics studies. The scope of the journal is to address the latest advances in theoretical ...

The study presents the multiphysics modeling of bio-aerosols generated from human respiratory impulses such as coughing, sneezing, breathing, and talking. These droplet-packed viruses exploit the influence of airflow for effortless transmission, rendering them a potential health risk to individuals in the same indoor environment. To gain insight into the transmission of these airborne particles, ...

Manufacturers consider carbon fiber as a wonder material for the world's economy. Its distinctive combination of high strength and low weight has helped drive the wind power revolution and make aircraft and ships more fuel-efficient. In addition, the carbon fiber structures can function longer and are more rigid than the traditional metallic models, making them more resilient in cold and more efficient ...

Due to the outbreak of Covid-19, negative pressure operating room (NPOR) are strongly recommended to be applied to prevent spreading virus from infected patients to adjacent rooms during surgery procedures. However, there have been few experimental studies on the effect of OR pressure difference on the surgical microenvironment. This study aims to experimentally investigate the airflow distribution ...

The fluids have been around us for as far as we know and it enabled us to cross the oceans, ride the winds, shortens the distances, and much more. Computational Fluid Dynamics (CFD) has extended our understanding of fluids. Until today, the analytical solution of fundamental equations of fluid mechanics is a million-dollar award (referred to Clay Mathematics Institute). As engineers, let's leave ...
