| Comparison the experimental method with the numerical method is one way to know that numerical method can be to representative of the experimental method on a study. A numerical method can be applied in various aspects , one of them is to analyst the most important parameter change in temperature occurring in classrooms. Basically a method is an excess to simulate a propertie system that involves fluid flow , displacement heat , and the process of other physical. The simulation method works is to solve with equation of fluid flow (in a particular shape) includes and area desirable, with speisfic and known boundary conditions. With software ansys fluent 15.0 , we can conclude that if the results simulation can represent the experiment, we must have a small percentage of error that simulated conditions can resembling the actual condition . Through the condition simulation have resembling actual , so method simulation can be used to predict any placement position air freshener optimal to the next classrooms. Factors that can affected change the temperature classrooms covering, wall temperature in 26.5°C , the rate of flow of large speed fluid 3.92 m / s , the number of seats and the table that is in classrooms , position placement outlet fan and the position of Air Conditioner that affects the distribution of the direction of a fluid flow. |
