Abstract In this paper, the non-stationary incompressible fluid flows governed by the
Navier-Stokes equations are studied in a bounded domain. This study focuses on the timefractional Navier-Stokes equations in the optimal control subject, where the control is
distributed within the domain and the time-fractional derivative is proposed as RiemannLiouville sort. In addition, the control object is to minimize the quadratic cost functional.
By using the Lax-Milgram lemma with the assistance of the fixed-point theorem, we
demonstrate the existence and uniqueness of the weak solution to this system. Moreover,
for a quadratic cost functional subject to the More >
