Various models have been proposed for the SW-LISM plasma interaction to study the shape of the heliosphere. According to the Parker model (1961), when SW interacts with the interstellar plasma with a very weak magnetic field “comet- like” cavity is formed, called heliosphere. With the help of simplified assumptions, we solve the Parker model for heliosphere in addition with charge-exchange term and compare it with 3D MHD-neutral simulation results for the heliosphere. We develop a chi-square analysis to quantify the relative difference between 2D potential flow and 3D simulation model heliospheric models, and use this to optimize the flow model parameters to derive a simple model for the flow of SW in the inner heliosheath.
