Overview


Due to competitive pressures and legislation, the automotive industry has been faced with the need to increase fuel efficiency and reduce emissions, while shortening design cycles, reducing costs and increasing vehicle complexity. This has produced vehicles that have engines with increased power densities and accessory loads, with reduced cooling airflow.


Currently, only approximately one third of the total fuel energy provides useful mechanical work to drive the vehicle, one third is lost as heat to the vehicle thermal system, and the remainder is lost through the exhaust system. Heat lost to the thermal system must be dissipated to the cooling airflow and rejected from the vehicle.


Demands for shortened design cycles and reduced costs have led to major challenges in vehicle thermal management that cannot be met with traditional engineering practices. The only practical solution is to use simulation and virtual prototyping. Because of its various capabilities,flexibility, minimal manpower, required data resources, and ease of use, 1-D system models have been shown to be highly effective.


Many manufacturers have found that the speed of virtual prototyping has led to early identification of optimum systems designs. This has reduced the requirement for physical prototyping and thus greatly reduced time scales and costs. Both have led to more cost-effective vehicle designs and less environmental damage.


Here we discuss how the use of FLOWMASTER2 equips the engineer to meet the challenges of underhood thermal systems engineering.
