Computational Fluid Dynamics analysis of a bus air channel

The paper examines the Computational Fluid Dynamics analysis of a bus air conditioning system. The bus under examination has a capacity of 29 sitting and 25 standing passengers. The effectiveness and efficiency of the system were analyzed through the Anasys Fluent software. During the study, the experimental results were put in comparison with the outcome of CFD results. For clarity of CFD results and to reach a significantly close outcome, different error elimination techniques, such as Mesh error elimination, were applied for the betterment of the work. Besides, to be precise, two different turbulence models, k-ϵ Standart and k-ω SST models were applied to the indicated system for deduction of a suitable method. The air conditioning system is used to decrease the inner temperature of the bus from 30 to 16 C°. Therefore, the inlet temperature in the analysis was set to 16 C°. The experiments were conducted by the anemometer of the KIMO VT200 brand. The test was conducted on the left side of the bus and measurements were conducted on every outlet section and the effectiveness of the system was investigated. Finally, a suggested air optimal air channel design was proposed and CFD analysis results for the suggested system were demonstrated.
