چکیده
Abstract A hybrid numerical flux scheme is proposed by adapting the carbuncle-free modified Harten-Lax-van Leer contact (HLLCM) to smoothly revert (HLLC) in regions of shear. This scheme, referred as HLLCT employs a novel, velocity-based shear sensor. In contrast non-local pressure-based shock sensors often used carbuncle cures, sensor can be computed localized manner meaning that easily introduced into existing codes without having implement additional data structures. Through experiments, it shown able resolve layers accurately succumbing instability.

An Approximate Harten-Lax-van Leer Riemann Solver for Relativistic Magnetohydrodynamics
An approximate Riemann solver for the equations of ideal relativistic magnetohydrodynamics is presented. The solver belongs to the so-called Harten-Laxvan Leer (HLL, [1]) family of solvers where an initial guess to the characteristic wave speeds is given without any knowledge a priori of the solution. Our proposed method of solution generalizes to the relativistic case the classical five-wave H...
متن کاملHLLC solver for ideal relativistic MHD
An approximate Riemann solver of Godunov type for ideal relativistic magnetohydrodynamic equations (RMHD) named as HLLC (“C” denotes contact) is developed. In HLLC the Riemann fan is approximated by two intermediate states, which are separated by the entropy wave. Numerical tests show that HLLC resolves contact discontinuity more accurately than the Harten-Lax-van Leer (HLL) method and an isola...

متن کاملAn HLLC Solver for Relativistic Flows
We present an extension of the HLLC approximate Riemann solver by Toro, Spruce and Speares to the relativistic equations of fluid dynamics. The solver retains the simplicity of the original two-wave formulation proposed by Harten, Lax and van Leer (HLL) but it restores the missing contact wave in the solution of the Riemann problem. The resulting numerical scheme is computationally efficient, r...
متن کاملDesign and Construction of a Novel Tactile Sensor for Measuring Contact-Force, Based on Piezoelectric Effect
In this paper, design and construction of a tactile sensor for measuring contact-force is presented. Mechanism of measuring contact-force in this tactile sensor is based on impedance changing of piezoelectric crystal and voltage of different points in circuit as a result of applying force on the crystal. By considering a specific point in the circuit and recording the changes of its voltage, ma...
