Abstract

Fan sentrifugal yang sudah ada sebelumnya dirubah bentuk casing volutenya, sehingga merubah letak suction pada sisi radial dan menambah jumlah sudu impeller. Penelitian ini merealisasikan Fan dengan kontruksi elektromotor dengan shaft impeller dihubungkan dengan belt dan pulley. Pengunaan belt dan pulley untuk mengurangi efek rambatan panas secara konduksi dari putaran elektromotor terhadap bearing dan impeller.
Tujuan dari proyek akhir ini yaitu untuk mengetahui peforma dari Fan radial-crossflow backward Impeller ini yang meliputi kapasitas aktual, tekanan total Fan, daya, dan efisiensi Fan maka dilakukan dengan pengujian Fan. Setelah didapat data hasil pengujian peforma Fan ini akan dilanjutkan dengan simulasi numerik dengan menggunakan software fluent 6.3.26 secara tiga dimensi.
Akhirnya Dari hasil pengujian alat didapatkan data bahwa Fan radial-crossflow backward Impeller memiliki kapasitas actual sebesar 0,01048 m3⁄s, tekanan ∆Ptotal sebesar 83,0027 Pa, daya output aktual sebesar 0,8698 watt, daya teoritis fan sebesar 1,20565 watt, dan efisiensi isentropis yang dihasilkan fan sebesar 72,14 %. Pada simulasi numerik ketika melakukan iterasi hingga 3 jam dan mendapatkan hasil simulasi numeri untuk kontur tekanan, kontur besaran kecepatan, vektor kecepatan dan aliran pathlines. Tekanan ∆Ptotal fan yang dihasilkan pada simulasi numerik sebesar 107,145 Pa serta kecepatan pada sisi inlet sebesar 1,50438 m/s dan kecepatan pada sisi outlet sebesar 2,0768 m/s.

The pre-existing centrifugal fan is resampled the shape of its volute casing so that it changes the position of the suction on the radial side and increases the number of impeller spoons. This research realized Fan with electromotor construction with impeller shaft connected with belt and pulley. Use of belts and pulleys To reduce the conduction effect of heat ampocation from electromotor rotation to bearings and impeller.
The purpose of this final project is to find out the performance of this radial-crossflow Fan which includes actual capacity, total Fan pressure, power, and Fan efficiency then done by Fan testing. After obtaining the data of Fan peforma test results will be continued with numerical simulation using fluent software 6.3.26 in three dimensions.
Finally, the test results of the tool obtained data that Fan radial crossflow has a actual capacity of 0.01048 m3/s, . ∆Ptotal fan pressure of 83,0027 Pa, actual output power of 0.8698 watts, theoretical power Fan of 1,20565 watts, and isentropis efficiency produced by Fan of 72,14 %. In numerical simulation when iterating for up to 3 hours and get modeling results for contour of pressure, contour of velocity, vector of velocity and pathlines. ∆Ptotal fan pressure produced in the numerical simulation was 107,145 Pa and the speed on the inlet side was 1.50438 m/s and the outlet side speed was 2.0768 m/s.
