項目背景：飛機為什么會飛？其中的原理相信很多人都有聽說過，由于機翼上表面的彎度大于下表面的彎度，上表面氣流的流速整體上要高于下表面的氣流速度，根據(jù)伯努利理論，機翼上下表面就會產(chǎn)生一個壓力差，提供向上飛機的升力。同時，車頭造型的設(shè)計中涉及到的流體力學(xué)因素眾多，比如車頭的邊角、車頭的形狀及高度等，人們發(fā)明了流線型汽車。本項目則將主要探討流體物理學(xué)在飛機與汽車車身設(shè)計中的應(yīng)用，明確流體物理學(xué)對汽車與飛機外形構(gòu)造發(fā)揮出的重要作用，能夠讓汽車與飛機造型的構(gòu)造更加合理，保證合理協(xié)調(diào)空氣及車輛之間的相互作用力，為汽車與飛機的行進便利創(chuàng)造條件。Why does the plane fly? The principle is believed that many people have heard that because the curvature of the upper surface of the wing is greater than the curvature of the lower surface, the flow velocity of the upper surface is generally higher than the flow velocity of the lower surface. According to Bernoulli's theory, there will be a pressure difference between the upper and lower surfaces of the wing to provide the lift of the upward aircraft. At the same time, many hydrodynamic factors are involved in the design of the head shape, such as the corner of the head, the shape and height of the head, etc. People invented a streamlined car. This project will mainly discuss the application of fluid physics in the design of aircraft and automobile body, and clarify the important role that fluid physics plays in the shape and structure of automobile and aircraft, which can make the structure of automobile and aircraft shape more reasonable, ensure the reasonable coordination of air and the interaction between vehicles, and create conditions for the convenience of automobile and aircraft.

項目介紹：流體的運動存在于人類活動的方方面面，從生理流動到飛機和汽車，工程師必須學(xué)會預(yù)測流體的行為，以設(shè)計設(shè)備和系統(tǒng)來處理和操縱流動。本項目將以汽車、飛機為例，探究流體物理學(xué)在工程中應(yīng)用。從流體的特性入手，分析流體的速度、流量、壓力、流體靜力學(xué)知識，從伯努利方程入手分析車輛與飛機的運動阻力與升力。本項目重點還原了飛機、汽車的翼型設(shè)計過程中流體物理學(xué)所占有的重要地位。學(xué)生將在導(dǎo)師的指導(dǎo)下以科學(xué)的方法記錄并且分析研究結(jié)果，在項目結(jié)束時提交項目報告，進行成果展示。

The motion of fluids exists in every aspect of human activity, from physiological flows to airplanes and automobiles, and engineers must learn to predict the behavior of fluids in order to design devices and systems to handle and manipulate the flow. This project will take automobiles and airplanes as examples to explore the application of fluid physics in engineering. Starting from the characteristics of the fluid, the velocity, flow, pressure, and hydrostatic knowledge of the fluid are analyzed, and the motion resistance and lift of vehicles and aircraft are analyzed from the Bernoulli equation. This project focuses on restoring the important position of fluid physics in the airfoil design process of aircraft and automobiles. Under the guidance of the instructor, students will record and analyze the research results in a scientific way, submit a project report at the end of the project, and display the results.
