A non-linear observer for unsteady three-dimensional flows
A method is proposed to estimate the velocity field of an unsteady flow using a limited number of flow measurements. The method is based on a non-linear low-dimensional model of the flow and on expanding the velocity field in terms of empirical basis functions. The main idea is to impose that the coefficients of the modal expansion of the velocity field give the best approximation to the availa...
متن کاملOptimum Shape Design for Unsteady Three- Dimensional Viscous Flows Using a Non- Linear Frequency Domain Method
This paper presents an adjoint method for the optimum shape design of unsteady three-dimensional viscous flows. The goal is to develop a set of discrete unsteady adjoint equations and the corresponding boundary condition for the non-linear frequency domain method. First, this paper presents the complete formulation of the time dependent optimal design problem. Second, we present the non-linear ...

متن کاملThree Dimensional Non-linear Radiative Nanofluid Flow over a Riga Plate
Numerous techniques in designing zones happen at high temperature and functions under high temperature are in a way that involves non-linear radiation. In weakly conducting fluids, however, the currents induced by an external magnetic field alone are too small, and an external electric field must be applied to achieve an efficient flow control. Gailitis and Lielausis, devised Riga plate to gene...
متن کاملParallel Computations of Unsteady Three-Dimensional Flows in a High Pressure Turbine
Steady (RANS) and unsteady (URANS) numerical simulations of three-dimensional transonic flow in a high-pressure turbine have been conducted. The results are compared by evaluating differences in contours of total pressure loss, contours of static pressure and wakes. Significant differences have been observed in these parameters, both qualitative and quantitative, which demonstrate that URANS si...
