The flow over the San Antonio class LPD 17 ship is simulated using Computational Fluid Dynamics (CFD) and parallel computers. Both steady-state and time-accurate results are presented for two yaw cases. The computations are done for inviscid flow with no turbulence modeling. Although the flow is highly turbulent and boundary layer effects may not be insignificant, the essential features, such a...

The pseudo-steady-state current due to a mediated enzymatic reaction on a microelectrode is characterized on the basis of theoretical analysis and numerical simulation. The steady-state current is proportional to substrate concentration when the enzymatic reaction is considerably faster than substrate mass transport via nonlinear diffusion. Under such conditions, the reaction plane, where the m...

An infinite-server queueing model with state-dependent arrival process and exponential distribution of service time is analyzed. It assumed that the difference between value rate total becomes positive starting from a certain number customers in system. In this paper, until reaching by system called pseudo steady-state period (PSSP). Distribution duration PSSP, its raw moments simple approximat...

A technique for accelerating global convergence of pseudo-transient continuation Newton methods is proposed based on residual smoothing. The motivated by the effectiveness local nonlinear smoothers at overcoming strong transients. In limit a small pseudo-time step, method reduces to smoothing technique, while in large steps, an exact recovered along with its quadratic properties. formulation re...
