Abstract
Developments in science and technology had prompted us to conduct various experiments to create a variety of things, which aims to facilitate and provide benefits for humans and beneficial to the continuation of the next study. Fluid flow across a lid-driven cavity was one of the important phenomena in the fields of engineering, especially fluid mechanics. Some real case such as the air flow in a room was an example of the occurrence of this flow. The method used was numerical simulations using OpenFOAM software to determine the value of the observation of the pressure distribution on the outer and inner wall (2D). Variations of Reynolds numbers used were 40, 100 and 1000. For the kinds of case's lid-driven cavity was used to provide information about the flow phenomena. Further analysis and comparison of the results of the data obtained in order to obtain lid-driven cavity flow phenomena with the potential of increasing the engine work well. From the simulation data obtained that in the case of lid-driven cavity for Reynolds numbers 40 obtained a value of 1.4079 Pa pressure distribution, which causes the formation of eddy (vortex). At Reynold's number of 100 obtained values of 0.738674 Pa pressure distribution which causes the formation of such eddy Reynold's number 40. While at Reynolds numbers 1000 led to declining value of the pressure distribution is equal to 0.226075 Pa. There was an interesting phenomenon, with the increasing of Re the vortex which formed higher and more to the center. Vortex area also greater.
