Modified Homotopy Perturbation Method for Solving Fractional Differential Equations
Journal of Applied Mathematics, 2014 The modified homotopy perturbation method is extended to derive the exact solutions for linear (nonlinear) ordinary (partial) differential equations of fractional order in fluid mechanics. The fractional derivatives are taken in the Caputo sense.

Geometry aware physics informed neural network surrogate for solving Navier–Stokes equation (GAPINN)
Advanced Modeling and Simulation in Engineering Sciences, 2022 Many real world problems involve fluid flow phenomena, typically be described by the Navier–Stokes equations. The Navier–Stokes equations are partial differential equations (PDEs) with highly nonlinear properties. Currently mostly used methods solve this
