Reduced‐order extrapolation technique for coefficient vectors of numerical solutions about fluid mechanics equation

For convenience, this study mainly focuses on the reduced order of coefficient vectors for the classical finite spectral element Crank–Nicolson (CFSECN) solutions about the two‐dimensional (2D) nonstationary Stokes problem, resulting that the reduced order model can possess the same basis functions...
