Analisa Pola dan Sifat Aliran Fluida dengan Pemodelan Fisis dan Metode Automata Gas Kisi
Abstract: This research is
conducted by using physical model and Lattice GasAutomata method for simple
flow patterns having different geometry. From physical model, the results are
speed pattern and fluid flow permeability. The resulted value of the
permeability by using physical model will be compared to the resulted value of
the LGA. The compared value of the LGA method is the value with angle 5o, 10o
and 15o by using laboratory scale. These angles are chosen due to it’s the
lowest error compared to those of other angles. In thephysical model the lowest
permeability value is gotten from the pattern of straight geometry 60o with
value 0.201 x 10-6 m2 and the highest permeability value is from pattern of
turn 2 with value 0.341 x 10-6 m2. While by using LGA method the the lowest
permeability value is pattern of straight 60o with value 0.209 x 10- 6 m2 while
the the highest real permeability value is pattern of turn 2 with value 0.344 x
10-6 m2. From the comparison data of permeability the results of error are
3.74%, 0.7% and 4.2% for the angle of 5o, 10o and 15o, respectively.
