Fishers and Boussinesq equation is solved by introducing an unconventional procedure known as Homotopy Perturbation Method (HPM). This procedure is proposed for working out linear and non-linear partial differential equations. We have solved three examples of Fishers and two problems of Boussinesq equation by introducing the HPM and the consecutive solutions are thereby acquired. The swift approach...
In the present paper, following Jeffery [6] and Rarity [18] an attempt has been made to obtain the initial time and distance at which the jump discontinuity first appears on the wave front in the case of steady fluid with several state variables in two dimensional steady supersonic flow. The result corresponding to two energy modes dissociation and vibrational are also obtained and discussed.
