The objective of the present project is to investigate electromagnetic-hydrodynamics phenomena of atmospheric plasmas and electrohydraulic discharge in gas, liquid and solid multi-phase systems.  Atmospheric pressure thermal (APTP) and non-thermal plasmas (APNTP) were used for gaseous pollution control of acid gases (NOx, SOx, HF, HCI, etc.), greenhouse gases (PFC, HC, HxOy, etc.), toxic gases (NF3, volatile organic compounds).  ozone-depleting gases (CFCs, halon), etc., and the most recently for solid, liquid and gaseous fuel reforming in energy industries.  Electrohydraulic discharge ED, i.e., discharge inside water or liquids, were used for drinking and waste water treatments using their oxidation and reduction processes as well as excellent in activation capability.  However, the role play by the electromagnetic hydrodynamics EMHD is not well understood as well as their the other physical and chemical detail processes in multi-phase systems, hence the optimization of the industrial processes applied these APTP, APNTP and ED are not well achieved.The program proposed here is an expansion of many recent phenomena observed in atmospheric pressure thermal and non-thermal plasmas in a multi-phase system.  Based on advanced PIV imaging, EMHD shows surprised phenomena in gas and liquid single phase flow such as EMHD generated wake, von Karman type voltex, on-set of turbulence etc. under the very low Reynolds number.  The physical mechanism of these phenomena, as well as pressure drop reduction, pumping effect, drag reduction, flow regime transition are the forces of the present study.  For a multi-phase system, EMHD void and solid migration, shockwave/pressure wave generation and propagation, cavitation, thermophresis etc. will be an additional phenomena to be investigated.
