Tesla valve applications for passive flow enhancement in micro fluidic applications are promising, because of its design of no-moving-parts. The effectiveness of the valve (measured via its pressure and thermal diodicity) can be increased by creating a multi-staged Tesla valve. Present study investigates the effect of varying Reynolds number (25-200) on flow rectification and thermal enhancement capability of a Tesla valve. Gamboa Morris Forster (GMF) design with a cross-section of 1mm2 and constant valve-to-valve distance (1mm) was utilized for this research. An arbitrary fluid with constant properties at a reference temperature was used as the working fluid. Periodicity in flow and thermal distribution are noticed in the latter part of MSTV. Average friction factor and pressure diodicity decreased with increasing Reynolds number whereas average Nusselt number and thermal diodicity increased. Correlations for friction factor, pressure diodicity, Nusselt number, and thermal diodicity were derived by fitting a non-linear curve fit model.
