Multiphase flows as a research area focus on the physics, modeling, and numerical simulation of flows involving more than one thermodynamic phase (e.g., gas–liquid, liquid–solid, gas–solid, or gas–liquid–solid systems). The field investigates interfacial dynamics, phase distribution, momentum, mass, and heat transfer between phases, and the onset of instabilities and flow regime transitions. Research emphasizes constitutive modeling (e.g., Euler–Euler and Euler–Lagrange frameworks), closure relations for interphase forces and turbulence, high-fidelity experimental diagnostics, and advanced computational methods to predict and control multiphase behavior in applications such as energy systems, chemical reactors, and environmental flows.
Researchers led by Collaborative Research Center (CRC) 1357 Microplastics at the University of Bayreuth have overturned a common scientific assumption in a new study: Microplastic particles do not all exhibit similar transport ...
