The thermodynamic behaviors of a system living in a curved space-time are different from those of a system in a flat space-time. We have investigated the thermodynamics for a system consisting of relativistic massless bosons. We show that a strongly curved metric will produce a large enhancement of the degrees of freedom in the formulae of energy and entropy of the system, as a comparison to th...

This work investigates the Delaunay refinement for curved complexes. A manifold complex is defined as an unambiguous representation for the geometric objects required by a partial differential equation solver. The Chew’s and Ruppert’s Delaunay refinement algorithms, including an extension for curved complexes, are described under a new and arbitrary dimensional perspective. A theorem for strong...

In this work, a series of experiments and numerical simulations performed using volume-of-fluid approach were carried out to investigate the flow miscible viscous fluid systems through microfluidic focusing devices with one central inlet stream (with “fluid 1”) two lateral streams 2”). The combined effect viscosity ratio velocity on characteristics focused outlet was assessed in channels differ...

Particle image velocimetry (PIV) measurements near a curved boundary usually require efforts to deal with low tracer density, high shear gradient andwall reflection. To resolve these difficulties, we presented a near-wall measurement technique named interfacial PIV (IPIV) that could return a tangential velocity component and a tangential component of wall gradient [Nguyen TD, Wells J, Nguyen C....
