Initial Results

Partially-averaged Navier-Stokes (PANS) approach has been recently developed as a possible bridging model between Reynolds-averaged Navier-Stokes (RANS) method and large-eddy simulations (LES). The resolution control parameters in PANS are the fractions of unresolved kinetic energy (fk) and unresolved dissipation (fε). We investigate the fixed-point behavior of PANS and present some preliminary results obtained using this model. By comparing the fixed-point behavior of PANS and URANS (unsteady Reynolds-averaged Navier-Stokes) methods, the possible advantage of the former over the latter is explained. Initial results from two-dimensional simulations of flow past square results are also presented.

On The Road

Friction between cargo and vehicle’s deck has been considered among the supplemental means for securing cargo. Although friction coefficients have been determined as a function of different influencing factors, such measurements have been performed under laboratory controlled conditions that simplify vehicle vibration and cargo-deck stiffness and contact characteristics. In this paper a methodology is proposed to quantify cargo-deck friction coefficients under realistic field conditions throughout the kinematical analysis of the stopping of the cargo-carrying vehicle by effects of dragging the cargo on the vehicle’s platform. The vehicle is located on an inclined road segment while the cargo is lashed to a fixed point on the road, in such a manner that the vehicle can travel a certain distance before the lashing becomes tensioned and the cargo starts stopping the vehicle. While average values for friction coefficients correlated well with those reported in the literature, standard deviations represented up to 33% of such average values.

AbstractExistence principles are given for systems of differential equations with reflection of the argument. These are derived using fixed point analysis, specifically the Nonlinear Alternative. Then existence results are deduced for certain classes of first and second order equations with reflection of the argument.
