This work demonstrates improved magnetic field representation in Magnetohydrodynamic turbulence simulation, indicating less numerical dissipation.

The aim is to reduce numerical dissipation in subsonic turbulent flows using a new numerical scheme.
Compared several numerical schemes including Split-Roe, Split-Bouchut, and USM-BK.
Implemented the schemes in simulations of turbulent dynamo and simple vortex problems.
Measured kinematic Reynolds number and magnetic Reynolds number in ideal MHD flows.
The new USM-BK scheme shows reduced dissipation of kinetic and magnetic energy.
USM-BK ensures divergence of the magnetic field is constrained to zero close to machine precision.
Comparative analysis shows USM-BK achieves the highest Reynolds number among tested schemes.
