Kajian Efek Konfigurasi Geometri Vertical Expansion Loop Terhadap Nilai Tegangan Di Hot Brine Geothermal Power Plant

Abstract

The Geothermal FCRS and Power Plant projects focus on distributing steam and
brine fluids resulting from geothermal separation processes. There is a potential for
flashing in the brine fluid distribution within the vertical expansion loop area, which
requires detailed evaluation of stress and displacement values due to its categorization as a
critical line. This study employs computational fluid dynamics (CFD) to simulate fluid flow,
based on various height and width configurations of the loop geometry, to assess the
potential for flashing. The fluid simulation results are then used to compare the stress
analysis of dif erent loop geometries. The results indicate that flashing occurs in geometry
2 with a height of 9 meters. Furthermore, the stress analysis shows that the stress value in
geometry 1 is below the allowable stress limit, ef ectively reducing displacement values
caused by thermal expansion loads.
