Moustafa Boukraa,Tawfiq Chekifi +1 more
TL;DR: In this paper , a 3D transient numerical simulation of material flow and heat transfer during the FSW process is presented, in which the equations of energy, conservation of mass and momentum were solved in the Eulerian coordinate, and the spatially variable thermo-physical properties and the non-Newtonian viscosity for the flow of material was calculated taking into account the deformation velocity, the temperature and the properties of the material depending on the temperature.

Volume of fluid (VOF) method for the dynamics of free boundaries
C.W Hirt,B. D. Nichols +1 more
TL;DR: In this paper, the concept of a fractional volume of fluid (VOF) has been used to approximate free boundaries in finite-difference numerical simulations, which is shown to be more flexible and efficient than other methods for treating complicated free boundary configurations.

Formation of dispersions using “flow focusing” in microchannels
TL;DR: In this paper, a flow-focusing geometry is integrated into a microfluidic device and used to study drop formation in liquid-liquid systems, where both monodisperse and polydisperse emulsions can be produced.
Formation of droplets and bubbles in a microfluidic T-junction-scaling and mechanism of break-up.
TL;DR: Experimental results support the assertion that the dominant contribution to the dynamics of break-up arises from the pressure drop across the emerging droplet or bubble.

TL;DR: In this paper, a front-tracking method for multiphase flows is presented, which is based on writing one set of governing equations for the whole computational domain and treating the different phases as one fluid with variable material properties.
