OPTIMASI DIFFUSER PADA EXHAUST SYSTEM DENGAN CATALYTIC CONVERTER UNTUK SEPEDA MOTOR 110 CC DENGAN SIMULASI CFD ALIRAN FLUIDA

Diffuser Optimation at Exhaust System with Catalytic Converter for 110 cc Mopet with Fluid Flow CFDSimulation. CFD simulation used to get behavior of exhaust gas through catalyst, this result will be used to optimizegeometry form to perform uniform stream distribution to catalyst, and CFD Simulation will used to analyzebackpressure that happened at the model.Keywords: catalytic converter, selection of material, CFD simulation, diffuser optimizatio
