Customer Challenge

We needed to help our client to analyse the temperature distribution within a saloon as the treated air is delivered from a heating/cooling system. 


This analysis was needed to ensure the system’s suitability for end, middle and double deck cars

Scope

  • To analyse the temperature distribution within the saloon as the treated air is delivered from the heating/cooling system

Solution

  • Using NX9.0 software, we created fluid volumes based on provided geometry specifications.
  • Our software expertise allowed us to test the air distribution within the cars under a range of environmental conditions.
  • We were able to visualise flow using contours and vectors. This allowed all stakeholders involved to see and test temperature distribution.

Features

  • We used the latest STAR CCM+ and NX9.0 software for simulation, allowing for easy-to-understand visualization and measurement.

Benefits

  • The customer was able to see the potential distribution and pressure drop of the treated air through the car’s ducting
  • They were able to measure comfort within the saloon and determine the best summer and winter configurations.
  • Temperature distribution within the double deck saloon was assessed across 14 operating points to determine system effectiveness.

Integrity matters: Protecting against job search scams

It has come to our attention that scammers have tried to mislead people by fictitiously claiming to be employees of Quest Global or posing as authorized recruitment partners. These entities are misguiding job-seekers by promising well-placed roles with our company and asking candidates to pay for a certification course with a promise of reimbursement once they have joined. Kindly note, Quest Global conducts a formal interview process in our search for extraordinary people. We would NEVER ask candidates to pay for certifications at any stage of the recruitment process.
