“…The unsaturated and saturated steady state solutions to the initial value problem have been obtained by Rahamathunissa and Rajendran [10] using a variational iteration method. The variational iteration method was due to He [12,13,14] and it has been successfully used to solve various problems [15,16,17,18,19,20,21,22,23,24] including the mathematical chemistry areas [25,26,27,28,29,30].…”
