We consider applications of a new function, introduced by Kudryashov (Optik, 206:163550, 2020), to obtain solitary wave solutions of nonlinear PDEs arising in the domain of plasma physics, through their traveling wave reductions. The Kudryashov function, R, has several features which significantly assist symbolic computation specially in case of highly dispersive nonlinear equations. The method provides a simple, effective and straightforward algorithm for obtaining solitary wave solutions.
