A Shock Sensor - Based Second - Order Blended (Bx) Upwind Residual Distribution Scheme for Steady and Unsteady Compressible Flow
A new blended multidimensional upwind residual distribution scheme is introduced, which takes an advantage of stability and robustness of the N scheme and the high accuracy of the LDA scheme. The blending coefficie...

Modification of the Central-Upwind Scheme Providing C-property Implemented on Shallow Water Equations
Model of shallow water equations is used for simulation of free surface flows such as river flows, tsunami, floods etc. Special benchmark for numerical schemes is 'C-property' feature. In our study we propose modication of Central-Upwind...

On the discrete maximum principle for algebraic flux correction schemes with limiters of upwind type
Algebraic flux correction (AFC) schemes are applied to the numerical solution of scalar steady-state convection-diffusion-reaction equations. A general result and used for proving the DMP for a particular limiter of upwind type unde...

A linearity preserving algebraic flux correction scheme of upwind type satisfying the discrete maximum principle on arbitrary meshes
Various choices of limiters in the framework of algebraic flux correction (AFC) schemes applied to the numerical solution of scalar steady-state convection-diffusion-reaction equations are discussed. A new limiter of upwind type is ...

A priori error estimates for upwind finite volume schemes for two-dimensional linear convection diffusion problems
It is still an open problem to prove a priori error estimates for finite volume schemes of higher order MUSCL type, including limiters, on unstructured meshes, which show some improvement compared to first order schemes. In this pap...
