Rheological behaviour of low fraction ice slurry in Pipes and pressure Loss in Pipe sudden contractions and expansions
International Journal of Refrigeration, 2012Co-Authors: L. MikaAbstract:Abstract The paper presents the results of experimental research on up to 15% ice slurry made from 10.6% ethylene alcohol. It looks at the pressure Loss coefficient during its laminar flow through sudden contractions and expansions. The experimental investigations dealing with pressure Loss coefficients were preceded by considerations and calculations in the field of the rheological behaviour of the ice slurry. Similarly to what can be found in papers by some other authors, two different types of behaviour were observed, depending on the shear rate values: behaviour close to the Bingham model for the low shear rate region, and for high shear rate values, a power law with a shear thickening behaviour. To predict ice slurry behaviour in both the low and the high shear rate region, the modified Herschel–Bulkley rheological model was suggested. in this model, generalized correlations for the yield stress, the consistency coefficient and the flow index were proposed.

studi eksperimen evaluasi head Loss pada cussons friction Loss in Pipe apparatus dengan modifikasi orifice dan penggunaan gate valve globe valve dan ball valve
2020Co-Authors: Septian HidayatAbstract:CUSSONS friction Loss in Pipe apparatus adalah salah satu perangkat pengujian head Loss perpipaan berupa instalasi sistem perpipaan yang ada di Laboratorium Mekanika dan Mesin-Mesin Fluida. Analisa head Loss meliputi head Loss mayor dan head Loss minor. Sistem perpipaan yang digunakan pada peralatan uji CUSSONS friction Loss in Pipe apparatus menggunakan bahan material Polyvinyl Chloride (PVC) dan Acrylic. Fitting perpipaan terdiri atas long radius elbow 90°, standard radius elbow 90°, elbow 45°, sudden enlargement, sudden contraction, orifice, gate valve, glove valve, dan ball valve. Beberapa pressure tap dihubungkan dengan manometer raksa dengan specific gravity (SG) 13,6. Head Loss pipa dianalisis menggunakan formulasi Swamee-Jain dan persamaan Darcy Weisbach. Pompa sentrifugal single stage digerakkan oleh motor pompa MQC 175 dengan daya pompa 300 Watt dan putaran 2850 RPM. Pengujian melibatkan pengukuran pada tekanan suction dan discharge pompa. Pompa dapat beroperasi pada kapasitas maksimal 100 L/min. Pengujian menggunakan variasi debit pada debit 0 L/min hingga debit maksimal 100 L/min pada diameter 1 in dan 3/4 in dengan kenaikan 2 L/min. Modifikasi juga dilakukan pada line II dengan penambahan orifice (β=0,6) dan pada line III dengan penambahan gate valve, globe valve, dan ball valve. Dari hasil eksperimen diperoleh grafik hubungan friction factor (f) terhadap Reynolds number (Re) dan relative roughness (e/D) pada line I yang berbahan PVC dan line III yang berbahan acrylic. Nilai f pada pipa akan turun seiring dengan kenaikan Reynolds number dan nilai e/D konstan terhadap Reynolds number yang semakin besar. Pada pengujian head Loss minor, diperoleh grafik hubungan Loss coefficient (K_L ) terhadap Reynolds number (Re) pada masing-masing fitting yang digunakan pada line IV dan juga pada gate valve, globe valve, dan ball valve pada line III. Seiring dengan bukaan valve yang diperkecil maka head Loss yang dihasilkan semakin besar. Pada pengujian orifice (β=0,6) didapatkan grafik hubungan discharge coefficient (C_D ) terhadap Reynolds number (Re). Dengan rasio β yang dinaikkan dari 0,5 menjadi 0,6 maka nilai discharge coefficient yang dihasilkan juga meningkat seiring dengan kenaikan Reynolds number. Pada performa pompa, BEP didapatkan pada kapasitas 50 L/min dengan efisiensi tertinggi 43,27% dan titik operating point tidak dijumpainya pada kurva karakteristik kerja pompa. Penelitian dilakukan pada aliran turbulen hingga debit 50 L/min. ====================================================================================================================== CUSSONS friction Loss in Pipe apparatus is one of the testing devices for head Loss piping as an installed piping system in the Laboratory of Mechanics and Fluid Machines. The analysis of head Loss covers head Loss major and head Loss minor. Piping system used on test equipment CUSSONS friction Loss in Pipe apparatus use Polyvinyl Chloride (PVC) and Acrylic materiasl. The piping fittings consist of long radius elbow 90˚, standard radius elbow 90˚, elbow 45˚, sudden enlargement, sudden contraction, orifice, gate valve, glove valve, and ball valve. Some pressure taps are linked with a mercury manometer with specific gravity (SG) 13,6. Head Loss Pipe is analyzed by using the Swamee-Jain formulations and Darcy Weisbach equations. A single stage centrifugal pump is driven by MQC 175 pump motor with 300 Watts pump power and 2850 RPM rotation. The test involves measuring on the suction and discharge pump. The pump can operate at maximum capacity 100 L/min. Testing use varying flow rate on 0 L/min to maximum flow rate 100 L/min at a diameter of 1 inch and 3/4 inch with a 2 L/min rise. Modifications are also made on line II with of orifice (β = 0.6) additions and on line III with the additions of the gate valve, the globe valve, and the ball valve. The experiment acquired that there is the chart of friction factor (f) against Reynolds number (Re) and relative roughness (e/D) at line I with PVC material and line III with acrylic material. The f value on the Pipe will go down as the increase of Reynolds number and the value e/D is constant toward Reynolds number which gets more increase. The testing of head Loss minor is acquired that there is the chart of Loss coefficient (K_L) against Reynolds number (Re) in each of the fittings used at line IV and also at the gate valve, the globe valve, and the ball valve on line III. As the valve openings receded, the resulting head Loss gets more increase. At the testing of orifice (β = 0.6) it obtains the chart of discharge coefficient (C_D) against the Reynolds number (Re). With the ratio β raised from 0,5 to 0,6 so that the value of discharge coefficient resulted rises as Reynolds number mounts. At the pump performance, BEP is found at of 50 L/min capacity with a highest efficiency of 43.27% and the operating point point does not meet on the pump’s characteristic work point curve. The research is carried on turbulent flow to flow rate 50 L/min.
