Abstract
The effect of inlet pressure, pitch size, and varied mould channel on the flowability of
the propylene are studied in terms of the velocity, flow rate, volume of the propylene
in the mould, and ratio of the propylene to the total mixture. The study was conducted
by using the Computational Fluid Dynamic (CFD) simulation software, ANSYS
Fluent. The main focus of this project is to compare the flowability of the propylene
in the different mould channels. Based on the simulation, the flow of propylene
exhibits a proper flow when the inlet pressure is set at 25kPa. The volume of the
propylene in the mould was the highest which indicates less air cavity is formed
during the simulation. Meanwhile, when the pitch size is increased, the volume of
propylene in the mould increases too. However, the volume of propylene drops after
the pitch size is increased to 150mm due to pressure drop during the simulation. The
different grooves in the channel affect the flowability of the propylene. For an
instance the triangular channel allows more volume of propylene to fill up the mould
as compared with circular and rectangular grooved channels as the velocity of the
propylene is lowest in the triangular grooved channel, thereby improving the
flowability of the propylene.
