Özet:

This thesis is intended to study the fluid behaviour with a new approach through the particle simulation technique. The fluid is considered to be under static conditions, and the activity of fluid particles is simulated. The method in the approach is mathematically exact. Instantaneous velocities are calculated with simple algebraic equations. Hence high efficiency in CPU time is achieved. In order to validate the method, the probability density function of the Maxwell-Boltzmann speed distribution and the pressure are calculated and compared with the theoretical values. It is shown that the difference between the theoretical calculations and the present method, providing the associated speeds of the Maxwell-Boltzmann distribution, is less than 3% for different system temperatures. The pressure values are also reasonably close to each other.
