“…Numerous research works have been done on the radiator of automobile engines in various aspects. Aravindkumar et al [5] examined a radiator tube with varying geometries using different nanofluids. The geometries were the straight and spiral tubes, designed with Catia, and the nanofluids included, for example, beryllium, oxide, copper oxide, silicon carbide, and tin oxide.…”

In automobile engines, it is commonly known that the proper removal of the excess heat, resulted from internal combustion, is of high significance in the prevention of numerous negative consequences. In this regard, the radiator has a pivotal role as the main component of the engine’s cooling system. Hence, its design and analysis are highly important, requiring more comprehensive failure and flow investigations. In this work, a Scania radiator is examined under the thermal and mechanical loads, followed by its analysis under the combined thermomechanical loading. Then, the flow characteristics, including the velocity, pressure, and enthalpy, are studied. In this regard, PTC-Creo software is utilized. The results demonstrate that the thermal stress causes seven times more displacement than the mechanical one. When they are combined, this value reaches 1.5 mm. Also, the maximum failure index value of the Tresca theory is around 4.58, observed at the inlet side of the radiator. Besides, this paper indicates that the PTC-Creo can be considered as a reliable and economical tool for simulation of industrial applications, such as the considered radiator of a heavy-duty cooling system.

“…The total heat transfer coefficient and entropy generation from panel radiators were investigated, and radiator size increases with increasing flow rate and supply temperature; the total heat transfer coefficient decreases with increasing radiator size and temperature but increases with increasing flow rate (Gelis, 2021). In addition, the most often used radiator tubes have a linear structure and are supported by straight flat plates to offer additional strength to withstand the force of air acting on the tubes, which can cause them to fail (Aravindkumar et al, 2021). In general, in the case of radiators, optimising the temperature distribution on the heater's surface in order to produce the highest potential radiator heat output is vital, but it is only solved once during the radiator's construction (design) and strength of the material (Dzierzgowski, 2021).…”

The current study is based on the structural analysis of radiators made of different materials to compare their effectiveness in the case of naturally aspirated and turbocharged diesel engines. For the analysis of the radiator structure, ABAQUS software was used. In the ABAQUS, static structural analysis was made to calculate the strength of the radiator. The said software is capable of calculating the strength of the radiator considering the boundary conditions (i.e., fixing at corners) as well as the loading conditions. It was observed that stresses generated while using an aluminium radiator were very high than those produced by steel radiators. According to the study, the following are the key findings for the steel and aluminium radiators. In the first case, while three corners were fixed, the steel radiator showed a deflection of 1.86 mm while aluminium exhibited 5.65 mm. However, in the second case in which the radiator had four fixed corners, the deflection of the steel radiator was 1.10 mm, while that of aluminium was 3.36 mm. Additionally, based on the deflections obtained from all investigations, it was found that radiators made of aluminium were more sensitive than those made of steel in both naturally aspirated and turbocharged applications. However, due to aluminium’s strong thermal conductivity, it is compatible with naturally aspirated engines in terms of thermal capacity. To combat turbocharged engine complications caused by high temperatures, such as thermal cracking, engine wear and tear, and so on, a steel-made radiator is more suitable than an aluminium radiator, hence mitigating the issues.
