Experiment and simulation research of engine cooling fan in dump truck

As an important component in engine cooling system, the cooling fan has a potent effect on the reliability and economy of the engine. To ensure that the performance of the cooling fan is satisfied with the practical working requirements, the following work is done. Firstly, the experiment of the cooling fan is carried out to get its performance data; Secondly, the performance distribution in actual working condition is simulated with the help of FLUENT; finally, the experiment result which has been fitted by MATLAB is compare with the simulation result. The relative error of the result between the experiment and the simulation is within the pale of 5%, which shows clearly that the performance data from experiments could meet the design requirements.
