Journal Article
Williams, H., Sprittles, J., Padrino, J. C., & Denissenko, P. (2022). Effect of ambient gas on cavity formation for sphere impacts on liquids. Physical Review Fluids, 7(9), Article 094003. https://doi.org/10.1103/physrevfluids.7.094003

Formation of a splash crown and a cavity following the impact of a sphere on a body of liquid is a classical problem. In the related problem of a droplet splashing on a flat surface, it has been established that the properties of the surrounding gas...

Efficient simulation of rarefied gas flow past a particle: A boundary element method for the linearized G13 equations (2022)
Journal Article
Padrino, J. C., Sprittles, J. E., & Lockerby, D. A. (2022). Efficient simulation of rarefied gas flow past a particle: A boundary element method for the linearized G13 equations. Physics of Fluids, 34(6), Article 062011. https://doi.org/10.1063/5.0091041

We develop a novel boundary integral formulation for the steady linearized form of Grad's 13-moment (G13) equations applied to a uniform flow of rarefied gas past solid objects at low Mach numbers. Changing variables leads to a system of boundary int... Read More about Efficient simulation of rarefied gas flow past a particle: A boundary element method for the linearized G13 equations.

We consider the linearized form of the regularized 13-moment equations (R13) to model the slow, steady gas dynamics surrounding a rigid, heat-conducting sphere when a uniform temperature gradient is imposed far from the sphere and the gas is in a sta...

Recently, Zhang and Padrino in (Int J Multiph Flow 92:70–81, 2017) derived an equation for diffusion in random networks consisting of junction pockets and connecting channels by applying the ensemble average method to the mass conservation principle....
