“…In this study, the Computational Fluid Dynamics/Computational AeroAcoustics (CFD/CAA) solver PowerFLOW based on the Lattice-Boltzmann Method is used to predict the transient flow field and corresponding flow-induced noise radiation [5][6][7][8][9][10][11][12] . The solver has been successfully applied in numerous industrial analyses, academic validations and investigations such as wind-noise, HVAC, fans, blower and wind-turbine problems [13][14][15][16][17][18][19][20][21][22][23][24] . Wall Pressure Fluctuations (WPF) near the tip gap are the focus of this paper, as the noise-generating mechanisms of interest for fans are expected to correlate to the measurement locations on the blade.…”

“…Introduction of stringent exhaust emission standards, lightweight materials in design, use of high performance and quieter automotive components has made it challenging for the NVH (noise, vibration and harshness) engineers, as the target to deliver a quiet and smooth vehicle is becoming difficult with every product life cycle. The market and customer expectation makes the HVAC system noise quality a question to be addressed as early as possible in the vehicle development process [1].…”

For the automotive industry, acoustic comfort is of increasing importance. Customer expectations and strong competition in the market play an important role to accelerate vehicle development activities. Although the primary function of HVAC (Heating ventilation and Air-conditioning) is thermal comfort of the occupant during ride; acoustic comfort is also important when it comes to customer satisfaction resulting in overall experience of the vehicle. Hence, prediction of cabin interior noise in the early design stage plays an important role in designing a superior quality product. In this paper, cabin interior noise levels generated by HVAC systems are predicted by using computational 1-D (one dimensional) analysis. 3-D (three dimensional) CAD geometry is designed using SOLIDWORKS and 1-D analysis is done on GT-Suite. Main purpose of this paper is to demonstrate how 1-D simulation can be an aid for a duct designer by predicting the NVH characteristic of HVAC Ducts and continuing the research to shorten the product development timelines.

“…Hence, the better air splits at the duct outlets and proper mixing of hot and cold airs were observed. Aissaoui et al (2015) validated the simulation model with experimental approach using real HVAC components. Both approaches were in good agreement, and the noise source was also identified in this study.…”

The presence of noises in the vehicle cabin is an annoyance phenomenon which is significantly affected by the heating, ventilation, and air conditioning (HVAC) system. There are very limited studies reported on the specific type of noise characterisation and validation for both model and vehicle system levels. The present study developed a model of HVAC system that reflects the operation as in real vehicle, and the investigation of the HVAC components were carried out individually to determine which component contributes to the humming-type noise and vibration. The study was conducted under two conditions; idle speed of engine (850 rpm) and operating condition (850-1400 rpm). A ixed blower speed and fullface setting were applied throughout the experimental process. Three different sensors were used for the experiment, which are: accelerometer, tachometer, and microphone. From the results, the compressor and AC pipe components have contributed the most in generating the noise and vibration for both the model and vehicle systems. The findings also highlight that the humming-type noise and vibration were produced in the same operating frequency of 300-400 Hz and 100-300 Hz for idle and operating conditions, respectively, and this result was validated for both model and vehicle system levels.
