Rapid advances have been made in the range of available designs and operational parameters as well as in the fundamental understanding of compact heat exchangers (CHEs). Since the majority of modern heat exchangers used for heating and cooling systems for vehicular applications are CHEs, keeping up to date with these advances is essential. This seminar will help you understand and be able to apply comprehensive information about the intricacies of CHE design, performance, operating problems and state-of-the-art-technology for car and truck applications.

Heat transfer affects the performance, emissions and durability of the engine as well as the design, packaging, material choice and fatigue life of vehicle components. This course covers the broad range of heat transfer considerations that arise during the design and development of the engine and the vehicle with a primary focus on computational models and experimental validation covering the flow of heat from its origin in the engine cylinders and its transfer via multiple paths through engine components.

Passengers’ thermal comfort inside car cabin is mainly provided by the heating ventilation and air conditioning system (HVAC). The main part of HVAC modules is placed under the dash board. An HVAC module is a compact system composed of various elements which are subject to airflow. The interaction between airflow and these in-duct elements generates noise inside car cabin. Furthermore, the blower used to blow air inside the cabin must overcome the pressure generated by HVAC elements. Noise is created and its level is linked to flow and pressure. HVAC noise is an important issue for car makers and automotive suppliers wishing to reach passengers’ satisfaction. Furthermore thermal-engine cars are more and more silent. Also hybrid and electric car sells are expanding around the world. HVAC noise became a main issue for automotive actors. In order to reduce its HVAC noises, Valeo and partners worked to develop several methods.

Five parameters are often used in acoustic modeling of porous absorption material, which are air flow resistivity σ, porosity φ, tortuosity α∞, viscous characteristic lengths Λ and thermal characteristic length Λ’. These parameters are not easy to be directly measured with high precision, especially the latter three parameters. FOAM-X is the software capable of identifying indirectly these parameters from impedance tube test results by virtue of Johnson-Champoux-Allard model, so becomes increasingly popular. However, its stability of parameter identification is rarely reported. This paper studies the factors to disturb the stability of FOAM-X on those porous absorption materials generally applied in vehicle interior trim (pure PET fiber, shoddy, PP/PET double-component fiber), such as the number of known parameters in advance, the frequency range, the vacuum bulk density, and so on.

The need in the automotive industry to understand the physical behavior of trims used in a vehicle is high. The PEM (poro-elastic method) was developed to permit an explicit representation of the trims in the FEM full vehicle models and to give tools to diagnose the effect of the trims and test design changes (porous material property, geometry…). During the last decade, the evolution on software and hardware sides have allowed to create models with a highly detailed trim description (Porous material using the Biot parameters, plastic trims...). These models can provide a good correlation up to 400Hz against the measurements compared to the classical NSM methodology which shows limitations.

Abstract Nowadays, investigating underhood airflow by using numerical simulation is a standard task in the development process of passenger cars and commercial vehicles. Numerous publications exist which deal with simulating the airflow through the engine compartment of road vehicles. However, hardly anything can be found which deals with off-road vehicles and nothing exists which focuses on snowmobiles. In the presented paper the airflow and the thermal conditions inside the engine compartment of a snowmobile are investigated by the usage of computational fluid dynamics (CFD) as well as experimental methods. Field tests at arctic conditions have been conducted on a serial snowmobile to measure temperatures inside the compartment and to gain realistic boundary conditions for the numerical simulation. Thermocouples (type K) were attached under the hood to measure exhaust, air, coolant and surface temperatures of several components at previously defined load cases.

The intersection is happening. The intersection between the vehicle and the product world is finally happening. And one quick walk on this year’s CES at Las Vegas and NAIAS at Detroit will ascertain the right confluence of the same. Albeit the apparent differences in the lead-time of the development processes, there is a lot to be cross-pollinated between these two not-so-distinct ecosystems. Because fundamental core sits the end user – the human being. And prevalent school of thoughts in both the disciplines are rightfully acknowledging the human centricity needed to plan for and design “objects” and “services” as an seamless offering. Gone are the days to just push metal or cheap plastic artifacts to the consumer, as that definition of consumer itself is changing.

In this talk, we will explore some conceptual use cases of Augmented Reality in manufacturing and other industrial applications, and the technology gaps that currently exist preventing them from turning into a reality. We’ll elaborate on this theme by looking at how current marketing for this technology has led to over-inflated expectations for what exists today, and the effect that is having on its perception outside of the community. To continue we will look at work being done both in industry and academia to address these technology gaps and how we are moving closer to meeting those expectations, and finally we’ll uncover the huge benefits in manufacturing operations once we are successful.
