Abstract Here we determine whether entropy drives planar turbulent jets into round turbulent jets. Determining when a jet flow transitions from one symmetry to the next is an important but incompletely resolved problem. The constructal view argues th

Lateral displacement arrays are useful for separating particles such as blood cells and sand from carrier fluids. These arrays consist of staggered posts, which allow smaller particles to follow streamlines and larger particles to flow around the pos

Particle separation is an important process step across many fields. One technique being applied for separating solids such as blood components or sand particles from carrier fluids is the use of arrays of aligned posts called deterministic lateral a

High-level radioactive waste stored at the Hanford Site near Richland Washington will be retrieved, transported, treated, and concentrated prior to final vitrification. This waste, stored in million-gallon underground tanks, is to be retrieved and tr

Here we explore the relationship between effective cleaning/clearing radii, ECR, and critical suspension velocities, Ucs. Although one set of physics controls both the radial extent of erosion (i.e., the ECR) and the velocity needed to erode from the

Here we model release of multidrug cocktails from small micelles. As most emerging anticancer agents remain sparingly soluble in water, they require carriers such as poly(ethylene glycol)-block-poly(D,L-lactic acid) (PEG-b-PLA) micelles to enhance th

Here we evaluate the influence of mucus layers on the evaporation time and transport of enveloped viruses, including SARS-CoV-2. Enveloped viruses must remain moist to be fully infective. Yet, the simple but enduring Wells model based on water drople

Here we evaluate critical shear stresses for erosion under laminar jet flow. To date critical shear stresses for erosion, as embodied in Shields diagrams, have largely been developed for turbulent flow both experimentally and mathematically. However,
