This study aims to determine the effect of changes in nozzle geometry on two-phase flow on the performance of the liquid-gas ejector. The method used is by conducting an experiment whose stages include: determining the nozzle geometry parameter, primary flow rate, and secondary flow rate. Then carry out tests on the installation of liquid-gas ejectors and collect data. The test is done by alternating the nozzle geometry, primary flow rate, and secondary flow rate. Next, analyze the data that has been collected to get the efficiency or performance of the liquid-gas ejector from changes in the nozzle geometry. The results showed that increasing the nozzle geometry tends to cause a decrease in the efficiency and coefficient of the nozzle. The maximum efficiency produced by each nozzle with a geometry of 0.57; 0.64; 0.71; 0.79 and 0.86 respectively were 24.33%, 23.43%, 8.19%, 16.21%, and 7.96%.

This water flow has two types, namely laminar flow and turbulent flow, the forces generated from these two flows are also different. Turbulent flow tends to produce a greater force and can lift object masses better than laminar flow. Therefore, a vortex turbine has emerged which utilizes turbulent flow as a waterwheel drive, by directing laminar flow towards the cross section and converting it into turbulent flow by utilizing the force of gravity and The cross-sectional shape forms a whirlpool that can move a waterwheel and turn a turbine. The number of blades is very influential on the performance generated from the vortex turbine and affects the resulting output, be it voltage, current, rotational speed, torque and efficiency. In this study, the best results were shown on blades with a total of 6, at a rotational speed of 141.3 rpm; at the voltage shows the result of 0.28 volts; at current it produces 44 mA; at Torque (Nm) 0.22 Nm; and the efficiency is 76.5%.","PeriodicalId":31503,"journal":{"name":"Turbo Jurnal Program Studi Teknik Mesin","volume":"45 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79213399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Betel nut that has a high selling price, was an old betel nut that has been dried. Various forms of betel nut that were sold in the market include whole betel nut, split betel nut and sliced betel nut. The purpose of this study was to find out the effect of the spin speed of the peeling mechanism on the timing and peeling result, and to find out the best interaction between the spin speed and the number of peeling rods that able to producing the best peeling efficiency. The method used in the study was a randomized design experiment consisting of two factors: spin speed (1000 rpm, 1200 rpm, 1400 rpm, 1600 rpm) and the number of peeling rods (12, 18 and 24) with 12 testing interactions. The main parameter observed was the percentage of peeled fruit with whole condition. The performance test result proved that the increase of the spin speed peeling mechanism has an effect on the efficiency of time, when the speed spin of the peeling mechanism increases, the time it takes to peel the dried betel nut was decreases. But this condition was not directly proportional to the increasing percentage of dried betel nut that was whole peeled. The best peeling interaction was at a speed of 1400 rpm, with 18 peeling rods. This interaction produced peeling efficiency, 88% of whole peeled fruit, 12% of split peeled fruit and 0% of the unpeeled fruit.","PeriodicalId":31503,"journal":{"name":"Turbo Jurnal Program Studi Teknik Mesin","volume":"72 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87636123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results obtained from the pyrolysis reactor process are charcoal and liquid smoke. The existing air will accelerate the process of biomass oxidation, but if there is excess air it will cause combustion of the biomass so that most of it will be oxidized and decomposed into smoke and this will cause less charcoal yield. However, without air, the pyrolysis process will take longer. Therefore, an ideal air requirement is needed so that the effectiveness of this biomass pyrolysis process can be maintained because it will produce optimal charcoal and liquid smoke. The purpose of this research is to find out how many air pipes for the pyrolysis reactor are needed in this combustion process and how long the time and temperature of the pyrolysis process combustion and how much charcoal and liquid smoke are obtained. This research was conducted at the Mechanical Engineering Laboratory of the University of Muhammadiyah Metro, this study used a pyrolysis reactor with a diameter of 40 cm, height 50 cm, air pipe diameter inch with variations in the number of 1,3 and 5.
