Stochastic estimation of Green's functions with application to diffusion and advection-diffusion-reaction problems
Russell G. Keanini, Jerry Dahlberg, Philip Brown +4
A stochastic method is described for estimating Green's functions (GF's), appropriate to linear advection-diffusion-reaction transport problems, evolving in arbitrary geometries. B…

On the physical mechanisms underlying single molecule dynamics in simple liquids
Russell G. Keanini, Jerry Dahlberg, Peter T. Tkacik
Physical arguments and comparisons with published experimental data suggest that in simple liquids: i) single-molecule-scale viscous forces are produced by temperature-dependent Lo…

Stochastic rocket dynamics under random nozzle side loads: Ornstein-Uhlenbeck boundary layer separation and its coarse grained connection to side loading and rocket response
R. G. Keanini, Nilabh Srivastava, Peter T. Tkacik +2
A long-standing, though ill-understood problem in rocket dynamics, rocket response to random, altitude-dependent nozzle side-loads, is investigated. Side loads arise during low alt…
