Simulating Complex Gear Box Lubrication Cases Using CFD

Gearboxes transmit power from generators to consumers. Proper lubrication of the rotating gears and bearings is essential for the performance and lifetime of the boxes. Designers must make sure that enough oil reaches the rotating parts, whether it is applied by grease or splash/forced spray of industrial oils. CFD is a great tool for achieving this goal as it can compute the immiscible motion of the oil–gas phase as well as the temperature of components in gearboxes.

In this webinar, we present industrial case studies in which Ansys Fluent CFD solutions for gear box lubrication were applied, resulting in good agreement with the test data. We also introduce an end-to-end automated workflow, ACT-Gearbox, which eases the inherent simulation challenges and improves productivity.

Accurately Predict Automotive Aeroacoustic Noise for a Quieter Ride

To gain a competitive edge as design challenges increase in the automotive industry, accurate prediction of aerodynamic noise is vital. The reduction of wind noise is becoming even more important for hybrid and electric vehicles, as the powertrain noise level is reduced and voice activation systems become more prominent. Fan acoustics, HVAC blower acoustics, compressor noise, duct noise, tire noise and other vehicle sounds must also be minimized for a quieter ride.

Ansys can help solve some of these acoustic design challenges for different operating conditions, including:

  • Noise performance for different design and operating conditions
  • Location and nature of noise sources
  • Effects of active and passive noise treatments

Optimizing Electric Motor Performance with CFD

Design and optimization of high-performance electric machines (e.g., motors and generators) require a multistage process to account for three major performance metrics: electromagnetic, structural/acoustic, and thermal. Traditionally, designs were based on a single physics and were conducted by separate engineering groups. Now, by using a multiphysics and system platform, you can consider all critical design goals simultaneously without compromising solution accuracy.

In this webinar, we’ll discuss accurate CFD/thermal solutions that enable faster, more reliable and more efficient electric machine designs, including:

  • CFD thermal model creation for a water-cooled electric motor
  • One-way and two-way coupling between electromagnetic and CFD solvers
  • Tips and tricks on modeling oil-spray cooling of electric motors
  • Creation of a thermal reduced-order model (ROM) for system modeling
