Automotive Water Cooling System Analysis Subject to Time Dependence and Failure Issues

Abstract

In an automobile engine, the heat transfer cannot be possible without cooling system support. The cooling system has a great importance in the engines. It coolants overheat of the engine, and prevents it from breakdown, that's why a highly reliable cooling system is the necessity of every engine but there are many failure issues with a cooling system which are time dependent. This paper investigates the performance of a water cooling system with the consideration of their significant components by taking the attention of three types of time dependent failure issues while the water cooling system is maintained by the sufficient repair facility. It is obvious that in the lack of maintenance, failure issues in water cooling system lead with the increment of time. Maintenance and operating costs of water cooling system affect the economy of overall engine very much, so, it is necessary to be aware about overheating of engines during peak ambient conditions when it is operated with full capacity. Hence, a Mathematical model of water cooling system is proposed by using the Markov process and supplementary variable technique.

Thermomechanical and Flow Analysis of a Typical Truck Radiator Using PTC-Creo

“…The author concluded that the brazing process is well-controlled in all production units and for different radiator technologies. Goyal et al [21] researched the reliability measures such as the availability, reliability, and MTTF of the automotive water cooling system considering the time and its failure rate parameters using Markov process and supplementary variable technique. Also, they investigated the sensitivity of these reliability characteristics to enhance the functioning of the water cooling system.…”
