SIMULASI NUMERIK ALIRAN UDARA VENTILASI DUA DIMENSIONAL DENGAN METODE BEDA HINGGA
Abstract: In CFD
(Computational Fluid Dynamics)
Simulation, the designer has the capability to design and redesign a
room over and over again, until the best and better design is found at a
relatively low price and less time compared to a scale experimentation. The
main goal of this research is to simulate two dimensional ventilation’s air flow
in various ventilation
systems. The algorithm
consists of seven stages
: set the
initial and boundary
conditions, calculate the
temporary velocity u with
ADI (Alternating Direct
Implicit) method, calculate
the temporary velocity v
with ADI (Alternating
Direct Implicit) method, calculate the
pressure value with
Line Gauss Seidel
method, the final
or real velocity value is obtained from correcting temporary velocity
values u and v with pressure value derivation, write and save data. From this
research, the following
observations were concluded
: The computer code
program which the
writer built could
generated two dimensional ventilation’s
air flow simulation,
ADI (Alternating Direction Implicit) method
with non-staggered grid
can generate visually
same simulation compared with
SIMPLER method, and
increasing the Reynolds number
proves to increase the air circulation within a room space.
