distribution of matter, homogeneous, inhomogeneous, Gravitational clustering, linear, non-linear, two-point correlation function.

In this paper a thermodynamic approach for non linear gravitational galaxy clustering in the expanding universe has been evaluated and implemented. Different techniques for understanding the clustering of galaxies have also been discussed. A two-point correlation function along with the thermodynamic quantities such as temperature and pressure has been used for the study and research. A Thermodynamic Parameter ‘b’ measures the influence of two particle correlation function. The value of ‘b’ depends on the two-point correlation function which intern is a function of density n and temperature T of the system in a grand canonical ensemble. As it is valuable to understand the functional form of b (n,T) and derive its expression in terms of n and T from equation of state. In order to evaluate ‘b’ a partial differential equation is developed by using laws of thermodynamics in combination with equation of state taking gravitational interaction between particles into consideration. The solution of the equation satisfies a set of boundary conditions for correlation systems and provides new ways for understanding gravitational clustering in expanding universe.
