Water jacket flow field verification method and system, readable storage medium and computer equipment

Abstract

The invention provides a water jacket flow field verification method and system, a readable storage medium and computer equipment, the method is applied to an engine, and the method comprises the following steps: performing CFD flow field analysis test on a cylinder cover water jacket of the engine according to CFD parameters to obtain first flow field data; basic parameters of the cylinder cover water jacket in the design stage are obtained, and a geometric model is constructed according to the basic parameters; rated parameters of the engine are obtained, and the input flow velocity and the output flow velocity of the engine under the rated parameters are obtained based on a bench test method; performing a flow field experiment on the geometric model according to the input flow velocity and the output flow velocity to generate second flow field data; judging whether the second flow field data is abnormal or not according to the first flow field data; and if the second flow field data is not abnormal, outputting the basic data of the cylinder cover water jacket as standard data in a design stage. According to the method, the difference comparison verification evaluation of the cylinder cover water jacket flow field and the actual flow field is realized, the design robustness is improved, and the problem of cooling cracking in the water jacket design is avoided.

Description

technical field [0001] The invention relates to the technical field of engine design, in particular to a water jacket flow field verification method, system, readable storage medium and computer equipment. Background technique [0002] With the rapid development of the automobile industry and the improvement of people's living standards, the engine design is gradually becoming mature. The engine cylinder head is an indispensable part of the engine, and its quality determines the sealing and heat dissipation of the engine. [0003] During the development process of the engine cylinder head, after the plan is determined and the preliminary CFD calculation is completed, the prototype of the cylinder head starts to be manufactured according to the design requirements. After the prototype is completed, various performance verifications of the whole machine are carried out. The cycle is generally 4-5 months. The production cycle is long and the cost is high. If the water jacket of...

Problems solved by technology

[0003] During the development process of the engine cylinder head, after the plan is determined and the preliminary CFD calculation is completed, the prototype of the cylinder head will be manufactured according to the design requirements. After the sample is produced, the performance verification of the whole machine will be carried out. The cycle is generally 4-5 months, the production cycle is long and the cost is high, and if the cylinder head water jacket is found to be unqualified in the later test, it will require a lot of manpower and material resources to solve the abnormality, and even the cylinder head needs to be remanufactured
