An effective heat transfer enhancement scheme is required to compensate for the decrease in heat transfer due to MHD effects in FLiBe based blanket design of fusion reactor. In present study, a twisted tape is selected as a potential candidate for a turbulence promoter, and a thermohydraulic behavior of turbulent flow of an electrically conducting fluid in a non-conducting pipe with twisted tape insertion under a transverse magnetic field is investigated. As a result, significant decrease of heat transfer performance is not observed compared with the same flow without the tape insertion because the heat transfer is dominated by the strong helical flow which is not suppressed by the magnetic field.
