Industrial applications: coating and drying processes
Suspension rheology
We carry out a simulation study to investigate rheology of particulate suspensions in shear flows.
Interfacial dynamic in complex fluids
Droplet including micro (or nano) sized particles show remarkably different deformation under shear flow. Various rheological behavior is captured in varying particles’ characteristics such as shape, charge and affinities among fluids.
Phase transition in soft matters
“Bimodal suspensions” can also be modeled by mesoscale simulation schemes. In this complex system, the microstructure is strongly affected by both size ratio and surface charge of components. It will induce the dramatic change of rheological properties.
Microfluidics
Mesoscale simulation is one of the robust approaches to study microfluidics. This technique has been applied to various applications, for example, droplet generation by using flow focusing devices and fluid flow around obstacles.
Active materials
Dynamics of self-propelled particles is also one of the fascinated topics in biology and fluid dynamics fields.
Industrial applications
We are interested in solving problems in industrial fields. (coating and drying processes)
