Abstract

Fan banyak digunakan dalam berbagai kebutuhan baik di industri, laboratorium, dan gedung-gedung perkantoran komerisal. Aplikasi Fan di Industri lebih banyak menjadi salah satu komponen parsial dari sebuah mesin produksi. Sedangkan aplikasi Fan pada gedung atau rumah-rumah lebih sering menggunakan sebagai penyegar udara dan circulator. Modifikasi dilakukan pada upstream yang terletak radial pada casing fan. Fan yang nantinya akan berfungsi sebagai alat pengering dimana temperatur fluida yang dialirkan tinggi. Banyak Fan diluaran yang memiliki kontruksi dari elektromotor terhubung langsung dengan impeller. Elektromotor dengan shaft impeller dihubungkan dengan belt dan pulley. Penggunaan belt dan pulley dilakukan untuk mengurangi efek rambatan panas secara konduksi dari putaran elektomotor terhadap bearing dan impeller.
Studi eksperimen fan radial crossflow forward impeller digunakan untuk mengetahui peforma fan. Simulasi numerik dilakukan untuk mengetahui karakteristik aliran fluida yang dihasilkan dari fan. Simulasi numerik menggunakan aplikasi CFD (Computation Fluid Dynamics), dimana hasil analisis nantinnya akan digunakan untuk mengetahui distribusi tekanan, kecepatan dan arah fluida. Pembentukan geometri fan menggunakan aplikasi GAMBIT, selanjutnya proses perhitungan dan analisis menggunakan aplikasi FLUENT.
Dihasilkan peforma dari fan 0.01970161013 m3/s, tekanan total sebesar 242.9122791 pa, daya input sebesar 422,4 watt, daya output 4.785763018 watt dan efisiensi fan 1.13%. Proses simulasi nilai tekanan total sebesar 705.725099 pa dimana tejadi kenaikan 463.957080998 pa. Didapatkan nilai tekanan total sebesar 729.666142 pa dimana tejadi kenaikan 486.7538629 pa. Didapatkan nilai kecepatan sebesar 2.8876913m/s pada saluran upstream dan 4.0632505m/s pada saluran downstream.

Fans are widely used in various needs both in industry, laboratories, and commercial office buildings. Fan Applications in Industry are mostly one of the partial components of a production machine. Meanwhile, fan applications in buildings or houses are more often used as air fresheners and circulators. Modifications are made to the upstream which is located radially on the fan casing. Fan which will later function as a drying device where the temperature of the fluid flowing is high. Many fans have the construction of an electromotor connected directly to the impeller. Electromotor with shaft impeller connected by belt and pulley. The use of belts and pulleys is done to reduce the effect of heat propagation by conduction from the rotation of the electromotor to the bearing and impeller.
Experimental studies and radial cross flow forward impeller are used to determine fan performance. Numerical simulations were carried out to determine the characteristics of the fluid flow generated from the fan. Numerical simulation using CFD (Computation Fluid Dynamics) application, where the analysis results will be used to determine the distribution of pressure, velocity and direction of the fluid. Formation of fan geometry using the GAMBIT application, then the calculation and analysis process uses the FLUENT application.
he performance of the fan is 0.01970161013 m3/s, the total pressure is 242.9122791 pa, the input power is 422.4 watts, the output power is 4.785763018 watts and the fan efficiency is 1.13%. Simulation process of total pressure value is 705.725099 pa where there is an increase of 463.957080998 pa. The total pressure value obtained is 729.666142 pa where there is an increase of 486,7538629 pa. The speed value is 2.8876913m/s on the upstream channel and 4.0632505m/s on the downstream channel.
