Each system's process is composed of a combination of the following five common modules: pipeline processing module, pipe connection module, initial level setting module, addition riser nipple module, and clash resolution module. Consequently, a prototype developed based on the formalized process produced a sanitary plumbing BIM model that is identical to the CAD drawings and has no clashes. This study contributes to the MEP BIM theory by identifying considerations for CAD-to-BIM conversion of sanitary plumbing system and formalizing the process reflecting them.","PeriodicalId":513408,"journal":{"name":"J.

Owing to their coolant and absorption characteristics, these broadly found in chemical engineering, biomedical engineering (expansion and contraction of veins and arteries), detection of cancer cells through magnetic nanoparticles, microchips and particularly in petroleum industry.\u0000 \u0000 \u0000 \u0000 This study focuses on investigation of nanofluid heat transfer applications inside a channel formed by expanding/contracting walls.

However, the fluid movement in the working domain is in reverse proportion for ${R}_e = 1.0,3.0,5.0,7.0$. Further, high absorbent walls (${A}_1 = 0.1,0.3,0.5,0.7$) controlled the motion for both ${alpha }_1 > 0$ and ${alpha }_1 < 0$, respectively. The addition of thermal radiation number ${R}_d = 0.1,0.3,0.5,0.7$ playing the role of catalytic parameter which imperatively increased the fluid temperature. Further, contracting walls and temperature ratio number ${theta }_r = 0.1,0.3,0.5,0.7$ reduced the temperature and this decrease is rapid in conventional fluid.\u0000","PeriodicalId":513408,"journal":{"name":"J.
