Modeling and analysis of the microfluidic chip

The work is devoted to the analysis of the hydrodynamic model of the Tesla valve, which allows to regulate the flow of liquid in the design of a microfluidic chip. When modelling fluid motion in complex Tesla valves consisting of several loops, one often resorts to analyzing a single loop and further extrapolating the results to the entire valve. To confirm or refute the validity of this method, valves consisting of one and eight loops are analyzed in the work. The resulting pressure difference and diodicity were studied. Based on the obtained data, it was revealed that the hydrodynamics of the Tesla valve is nonlinear and does not correctly generalize the results obtained for one loop to valves consisting of a larger number of loops.
