        abstract = {The flow of fluid and thermal characteristics is computed for a channel with a Tesla valve-configured valvular conduit. Through three-dimensional simulation, we will investigate the channel’s hydrodynamic performance as well as thermal performance effect of geometric parameters, flow directionality, and Reynolds number. The focus is on the flow rectification of Tesla valves and the mechanism of convective heat transfer without moving parts. The simulations of forward flow and reverse flow exhibit significant asymmetry in terms of velocity distribution, pressure drop, and heat transfer rates. Longitudinal vortices generated by forward flow stabilize the boundary layer and slightly enhance heat transfer. The reversal of flow creates transverse vortices. Turbulent structures can compress thermal layers and enhance heat transfer in geometry. Nusselt number, friction factor, and a new term measure directional difference: thermal diodicity index. The conduction angles and side channel lengths affect the valve diodicity and thermal efficiency. Heating a coil with a larger angle or volume generates more reverse flow than a circuit with a smaller angle and volume. The research also emphasizes the significance of geometrical optimization during implementation and the thermal performance pressure drop exchange. CFD models are validated with experimental data and are grid-independent. The design criteria obtained from the results allow for optimizing microchannel systems based on Tesla valve for thermal control of small heat exchangers, battery cooling and microfluidic devices. The current work enhances the comprehension of coupled fluid-thermal phenomena in valvular conduits and lays the foundation for a predictive framework ‘for device design of passive flow control and heat transfer devices based on Tesla valve.},
