This study investigates the turbulent flow and transport of a passive scalar in magnetohydrodynamic (MHD) channel flows influenced by magnetic fields. The main aim is to understand how different orientations of the magnetic field, specifically wall-normal, spanwise, and streamwise, impact the dynamics of scalar transport in electrically conducting fluids such as liquid metals. Direct numerical simulations (DNS) are employed to analyze the effects of the imposed magnetic field on the turbulent flow characteristics and scalar distribution. The results reveal that magnetic fields, particularly in wall-normal and spanwise orientations, significantly suppress turbulent scalar transport and alter the scalar distribution properties. This research highlights the critical association between magnetic field orientation, turbulence, and passive scalar transport, contributing to the understanding of flow processes in MHD systems, which are relevant in various industrial applications like continuous steel casting and crystal growth. The findings underscore the importance of the magnetic interaction in modifying turbulence and scalar distributions in MHD flows.
