Abstract: A new method to create a nano flow is introduced in this paper. This method is based on controlling the macroscopic properties of a region in a periodic flow. Combination of two controllable regions is explained for creating a flow field. This method can be used for creating a pressure gradient in a channel. Velocity, pressure and molecular density behaviors are studied in a uniform flow by increasing temperature level with constant temperature gradient between two controllable bins. We show that constant temperature gradient does not always lead to the same pressure gradient. Different temperature gradients are evaluated in this study. We show that higher temperature gradient always leads to higher pressure gradient and molecular density gradient along the periodic flow.
