Application of simulation technology in chemical engineering teaching to solve practical training problems

Thread Content

In traditional chemical engineering practical training, most students do not have any practical operations, and this kind of scene is very common. The introduction of simulation experiment teaching from Qinhuangdao Yuandao Technology Development Co., Ltd. has solved this problem to a great extent. Local comprehensive universities have limited funds for experimental construction, and the issuance rate of some experiments is low, which affects the cultivation of students' practical ability. The simulation training system is used to solve the problem that students cannot do hands-on and practical tasks in time-based teaching. * There is a serious shortage of funds. Advantages of chemical engineering simulation system teaching (1) Simulation experiments require low investment and easy maintenance. Chemical experimental equipment is generally more expensive and occupies a large area. For classes with many students, it is difficult to obtain one equipment per student. Simulation experiments are run by each student on the computer using simulation experiment software, which solves the problem of many students and few experimental equipment. That is, simulation training can give everyone a chance to do it. (2) The experimental operation is simple and the process flow is realistic. The chemical engineering experiment course uses the structure, graphics and image technology of the experimental device to conveniently, quickly and vividly reproduce the teaching experimental device, experimental process and results. This kind of teaching that is both concrete and vivid gives students an experience as if they were at the experimental site. Learning is not abstract, has a strong sense of reality, and is intuitive. (3) Automation of data processing, calculation, and analysis. Most of the data processing of chemical engineering principle experiments is a tedious process. Using simulation experiments, after recording the experimental data, in the data processing part, the computer can automatically list the results and automatically plot the data on the coordinate chart, and then accurately return and draw a continuous and smooth curve. * * Reduced data processing time. (4) The simulation experiment software is extremely scalable. Since the simulation experiment adopts modular development technology, it not only facilitates the expansion of the software, but also allows new experimental devices to be added, and teachers can add content as needed. How to conduct chemical engineering simulation teaching (1) Grasp the system structure as a whole. Simulation experiments should be synchronized with theoretical courses, and theory and practice should be combined to help grasp the overall layout of the simulation software as a whole. In order to learn simulation operations well, students must first be guided to grasp the layout of the simulation software as a whole and match the theories they have learned with the live scenes. Based on a solid theoretical foundation and supplemented by careful guidance from teachers, it is a matter of course to master the content of this link. (2) Grasp the system structure in detail. Chemical production lines are connected by numerous pipelines. To carry out simulation operations in a step-by-step and purposeful manner, it is not enough to just master the overall layout of the software. It is necessary to have a clear understanding of the direction and function of the pipelines, especially the key pipelines, that is, to grasp the system structure in detail. Only in this way can we avoid blindness and mechanical operation and change aimless passive imitation into purposeful active operation. * * Augmentology * The effect ； Of course, doing this well requires tacit cooperation between teachers and students. If conditions permit, you can visit and learn on the spot. * , to deepen the impression. (3) Introduce experimental assessment form in order to stimulate students’ learning * In order to improve students' enthusiasm, a system of assessment after completing simulation experiments has been implemented. Within the specified time, students independently complete a certain simulation experiment designated by the teacher, and the computer automatically scores. To achieve good results, you must master each simulation experiment proficiently. In short, the introduction of simulation technology into the teaching of chemical engineering theory courses can make the process analysis and design calculations in more abstract theoretical teaching have a certain degree of visualization effect, which is helpful for improving students' learning. * interests, cultivate their operational skills, and comprehensively and in-depth understanding of relevant studies. * Content has a positive effect.
