This research study investigates the influence of undercover design on three critical aspects of vehicle performance: water entering into air intake filter, Aerodynamic performance, thermal performance on vehicle engine room components (Condenser, Radiator and Air Intake System). Undercover serves the purpose of protecting Engine, underhood components and also improves aerodynamics of the vehicle. Through CFD simulations, various undercover design configurations: Full Undercover, no undercover and half undercover cases are evaluated to assess their effectiveness in mitigating the water ingress into the air intake system. Additionally, we explore the implications of these design alterations on the thermal performance and aerodynamic drag.

Climate across India varies from extreme Cold to extreme hot. As an objective to improve comfort to drivers during summer, it is mandate by Indian Government to introduce Air Conditioning in Trucks from June 2025. Air Conditioning system includes Evaporator, compressor, Condenser and expansion units. Condenser needs continuous air flow to reject the absorbed heat from driver cabin to surrounding air. This is possible by directing air through condenser by an external fan. For this condenser is remotely mounted with an electric driven fan or directly to the radiator-fan system. In this paper a case study is presented where Cooling system of a Non AC Intermediate Commercial Truck is modified for Air Conditioning application. Condenser is mounted on the radiator and the additional heat load is managed by a minor change in the system. Fan is operated based on coolant temperature and with additional controls for Air Conditioning. Simulations are done in a Thermal management software “KULI”.

In recent times, indoor air quality has become an important concern as it affects people's health and comfort. According to WHO report, air pollution causes 7 million deaths every year. PM2.5 has been identified as a key pollutant which impacts human health causing diseases like stroke, heart diseases, breathing issues, cancer and so on. In today's time, we travel by personal vehicle every day, commuting for hours. It is an extension to our homes. Unfortunately, due to frequent door and windows opening, the cabin air gets exposed to outside pollution, and we end up breathing pollutants. To mitigate the problem, air purifiers are added in the automobile. As people are becoming more aware and conscious about good air quality, there is a growing demand for cabin interior air quality solutions for automobiles. A popular approach is to add an air purifier inside cars like ones being used in our homes to bring down the PM2.5 levels.

Cooling module is used in vehicles for engine and Cabin cooling heat exchange with ambient. Cooling module generates flow induced noise due to cooling fan. Cooling module fan noise prediction at CAE level at vehicle level is not available in literature. Many researchers have done fan noise simulation at component level but to it is important to predict vehicle level noise when fan is mounted on a vehicle. Such simulations are transient and complex due to computational cost. Current paper discusses detailed methodology for component and vehicle level CAE simulation. Results of both scenarios are compared with experiments and correlation is established. Component and vehicle level noise simulation is carried out LBM (Lattice Boltzman) based software and tests were conducted in semi anechoic chamber. This paper also demonstrates test and simulation setup used for component and vehicle level acoustics CFD analysis.

Proton exchange membrane (PEM) fuel cells are one potential green energy option for fuel cells, which are becoming more and more popular in the energy production industry. Despite the fact that it continues to draw a lot of interest, many obstacles, such as enhancing performance, boosting durability and reducing cost are impeding the PEM fuel cell's commercialization. The performance of the fuel cell is affected by air/hydrogen feed and thus there is a need to regulate the supply manifold pressure at the cathode side of the fuel cell. A substantial amount of power is used when operating at maximum load, and fuel cells may experience oxygen starvation due to inadequate air. Maintaining a quick and adequate air concentration in the fuel cell cathode is essential to avoiding oxygen starvation and maximizing durability.
