Description :

　　Principles of Chemical Engineering Experimental Device - Bernoulli Experimental Device

　　Purpose of the experiment:

　　1. Familiarize oneself with the concepts and conversion relationships of various energies and pressure heads in fluid flow, and deepen the understanding of Bernoulli's equation.

　　2. Observe the variation of various energies (or pressure heads) with flow velocity.

　　Main configuration:

　　The Bernoulli experimental setup mainly consists of a water storage tank, a water pump, a high-level water tank, a rotor flowmeter, a Venturi tube, a pressure measuring tube, and a stainless steel frame.

　　The chemical industry can be said to make people both love and hate. Love "is because in life, from clothing, food, housing, transportation to various expenses, it covers all walks of life and can be said to be all encompassing; Hate "refers to the industry's" danger "," environmental protection "and other issues.

　　The comprehensive chemical production line is divided into three types of shell and tube heat exchangers according to the flow state of the shell side fluid: transverse flow, longitudinal flow, and spiral flow. Traditional baffle heat exchangers have lateral fluid flow in the shell side, which results in strong erosion of the heat transfer tubes. However, it is prone to flow and heat transfer dead zones, and the heat transfer area cannot be fully utilized. The flow resistance is high, and scaling is easy to occur. Moreover, when the flow velocity of the shell side fluid is high, induced vibration damage is prone to occur, which limits its application; The baffle rod heat exchanger achieves longitudinal flow of shell side fluid, exhibiting better heat transfer, low flow resistance, anti vibration and anti scaling performance. However, it also has the defects of insufficient compactness and poor heat transfer effect under low heat conditions; The spiral baffle heat exchanger realizes the spiral flow of shell side fluid, with a relatively smooth change in fluid velocity, and can effectively eliminate dead zones and backmixing phenomena.

　　The main purpose and configuration of the experimental apparatus for chemical engineering principles

　　Principles of Chemical Engineering is a highly practical technical foundation course and a core course in various chemical engineering majors. It belongs to the scope of engineering disciplines and applies the basic principles of natural sciences to analyze and process the physical processes in chemical production. The experiment of chemical engineering principles, like theoretical courses, is an important part of the entire teaching of chemical engineering principles. The two complement each other and play a crucial role in cultivating talents in chemical engineering and related fields. The main task of the chemical engineering principle experimental device is to undertake theoretical teaching, experimental teaching, and course design guidance for courses such as "Chemical Engineering Principles", "Chemical Engineering Fundamentals", "Fluid Flow and Heat Transfer", "Mass Transfer and Separation Processes" in relevant majors throughout the school.
