ABSTRACT
The aim of the paper is to present the influence of selected deflocculants on decreasing the hydromixture viscosity and as a consequence decreasing the wall shear stresses in a flowing medium. Adding deflocculants to improve the conditions encountered in a pipeline
during the hydromixture flow is called chemical processing. The experimental studies presented
in the article were performed for a hydromixture with a mass concentration of 20% and 43%
consisting mostly of solids with the averaged diameter ...

ABSTRAK
Transport characteristic adalah salah satu rheology ice slurry yang perlu diteliti. Transport characteristic adalah satuan energi pendinginan yang didapatkan dari ice slurry yang dialirkan dengan variasi kecepatan tertentu. Pada penelitian ini, ice slurry dibuat menggunakan campuran air tawar dengan 20% Monoethylene Glycol sebagai freezing depressant. Ice Slurry ini dibuat dengan ice slurry generator pada Laboratorium Pendingin Departemen Teknik Mesin Fakultas Teknik Universitas Indonesia yang mencapai suhu terendah -15 dengan 12 jam waktu pengoperasian. Ice ...

Silica sand slurry is a multiphase flow that consists of liquid and particle solids. Slurry flow characteristics are affected by particle size, particle distribution, particle concentrate, pipe geometry, flow regime, and viscosity factors. Spiral pipe is one of the solutions to increase drag reduction at a certain velocity and Reynolds number (Re). The aim of this experiment is to figure out the influence of using spiral pipe in increasing drag reduction of silica sand slurry ...
