Numerical analysis of the shock train evolution in planar nozzles with throat length [PDF]

open access: yesFME Transactions, 2023
In the present investigation, the behavior of compressible flow in planar nozzles with throat length is analyzed to determine the flow velocity range and pressure fluctuations in the throat section.

Direct numerical simulation of turbulent channel flow up to $\mathit{Re}_{{\it\tau}}\approx 5200$ [PDF]

open access: yesJournal of Fluid Mechanics, 2014
A direct numerical simulation of incompressible channel flow at a friction Reynolds number ( $\mathit{Re}_{{\it\tau}}$ ) of 5186 has been performed, and the flow exhibits a number of the characteristics of high-Reynolds-number wall-bounded turbulent ...

Numerical simulations of sunspots [PDF]

open access: yesProceedings of the International Astronomical Union, 2006
AbstractThe origin, structure and evolution of sunspots are investigated using a numerical model. The compressible MHD equations are solved with physical parameter values that approximate the top layer of the solar convection zone. A three dimensional (3D) numerical code is used to solve the set of equations in cylindrical geometry, with the numerical ...

Global convergence of RTLSQEP: A solver of regularized total least squares problems via quadratic eigenproblems

open access: yesMathematical Modelling and Analysis, 2008
The total least squares (TLS) method is a successful approach for linear problems if both the matrix and the right hand side are contaminated by some noise.

Numerical Simulation of Baroclinic Jovian Vortices [PDF]

open access: yes, 1994
We examine the evolution of baroclinic vortices in a time-dependent, nonlinear numerical model of a Jovian atmosphere. The model uses a normal-mode expansion in the vertical, using the barotropic and first two baroclinic modes.

Direct Numerical Simulation of Turbulent Flows Laden with Droplets or Bubbles

open access: yesAnnual Review of Fluid Mechanics, 2019
This review focuses on direct numerical simulations (DNS) of turbulent flows laden with droplets or bubbles. DNS of these flows are more challenging than those of flows laden with solid particles due to the surface deformation in the former.

Numerical Dynamo Simulations [PDF]

open access: yes, 2007
In this chapter, we review the progress in numerical modeling of the geodynamo made since 1995. Modern geodynamo models solve the fundamental equations of convection-driven flow and magnetic induction in a rotating spherical shell filled with an electrically conducting fluid.

Improved Bayesian Network-Based Risk Model and Its Application in Disaster Risk Assessment

open access: yesInternational Journal of Disaster Risk Science, 2018
The application of Bayesian network (BN) theory in risk assessment is an emerging trend. But in cases where data are incomplete and variables are mutually related, its application is restricted. To overcome these problems, an improved BN assessment model
