MUT1D: User-Friendly One-Dimensional Thermal Model
MUT1D is a microcomputer-based heat conduction model which uses implicit finite difference techniques to determine the thermal regime and track the movement of the phase change front in...

A Conceptual Model for Vertical Frazil Distribution in Turbulent Flows
A conceptual model is presented for the evolution of frazil over depth in a turbulent flow. The net upward migration due to buoyancy of the frazil is opposed by intermittent mixing induced...

Effects of Heterogeneity on Actinide Diffusion Rates in Tuffaceous Rock
The pore structure and mineralogy of Topopah Spring Tuff are heterogeneous on scales less than one cm. This heterogeneity creates spatial variation in transport rates for aqueous actinide...

Durability, Mechanical, and Thermal Properties of Experimental Glass-Ceramic Forms for Immobilizing ICPP High Level Waste
The high-level liquid waste generated at the Idaho Chemical Processing Plant (ICPP) is routinely solidified into granular calcined high-level waste (HLW) and stored onsite. A research...

The Integrated Performance Assessment in SKI Project-90
The SKI Project-90 is a performance assessment of a hypothetical repository system with KBS-3 features in crystalline rock. A large part of the effort has been to identify and characterize...

Apparent and Simple Diffusion Coefficients in Compacted Bentonite
Diffusion coefficients were experimentally determined in bentonite to evaluate the effectiveness of bentonite layers as a diffusion barrier to ionic transport away from high-level radioactive...

hpVersion of the Finite Element Method in Boundary Layer Problems
The performance of hp-version of the finite element method in the case of boundary layer problems of convection-diffusion type is presented. The method is also considered in the case of...

A Turbulence Model for Transverse Mixing in Rivers
A two length-scale turbulence model is developed to simulate transverse mixing prosesses in rivers. The dispersion of the effluent from the MUC (Montreal Urban Community) sewage treatment...

Gas Phase Turbulence Modification with Fine Particles in 2-D Duct Flow
The effect of a dilute suspension of fine particles on a two-dimensional turbulent duct gas flow is measured with hot-film anemometry. The flow field without particles is compared to the...

Chaotic Advection in a Shear Layer
The developing (in time) inviscid shear layer, although not yet in its turbulent regime, displays all the characteristics of chaotic advection. The corresponding Lyapunov exponent is strictly...

Computation of Flow Fields Induced by Hydroplant Releases into Lower Lock Approaches
A turbulence-based computational procedure was developed and applied to the prediction of flow fields in navigation installations induced by hydropower releases. The procedure uses a depth-averaged...

On Determination of Turbulence Model Coefficients for Anisotropic Reynolds Stress Closure Model
In this paper, the determination of turbulence model coefficients for anisotropic Reynolds stress model is discussed. The proposed model includes anisotropic Reynolds stress modeling and...

Computation of Wind Flow Around a Building
A numerical investigation of wind flow around a three-dimensional building is presented by solving weakly compressible flow equations, together with Smogrinsky's subgrid-scale...

Spatial Coherence in the Chaotic Dynamics of Multi-Degree-of-Freedom Elastic Impact Oscillators
In this paper, we describe a method for estimating the number of degrees of freedom needed to adequately model nonlinear structural systems. We apply the method to the study of chaotic...
