- Summary:
- Currently, noise pollution has become one of the majorenvironmental concerns. To address this, new noise standards andregulations are being introduced and mandate the tractor OEM'sto meet the defined noise levels. Fan noise from the cooling fan isone of the key contributors to the overall vehicle noise. Hence,the reduction of fan noise at the source is a very important andcritical task. Even though fan noise is broadband in nature itsaerodynamic noise sources are most dominant at the higher harmonicsof the blade pass frequency (BPF). Aerodynamic noise of a fan canbe varied by changing the fan geometry viz. blade profile, fanwidth and diameter, numbers of blades, and ring on its periphery.Cooling fan is an important component of the cooling system whichensures adequate airflow for radiator cooling and avoids engineoverheating with uniform heat dissipation. The important parametersthat need to be considered while designing a cooling fan are noiselevel, airflow, and power consumption. A good fan design shouldprovide a lower noise level while maintaining adequate airflow forthe engine. The various fan designs are numerically simulated usingexperimentally validated CFD and CAA techniques using FLUENT withappropriate boundary conditions to predict the airflow and noiselevel, respectively. With the aid of simulation, a new fan designwas developed with 7 blades and a ring on its periphery. Theoptimum blade profile ensured increased airflow for engine coolingand ring on its periphery avoids turbulence resulting in lessernoise. This project will also be considered for further validationplans on real-time vehicle applications to realize the objective ofdesign as a future scope of work
