About: The Department of Precision Instruments and Mechanology (DPIM) originated from the Department of Mechanical Engineering, School of Engineering, Tsinghua University, which was founded in 1932. The department is one of the earliest engineering discipline departments in China, mainly engaged in talent cultivation and scientific research in the field of advanced manufacturing, including Mechanical Engineering, Optical Engineering, and Instrument Science and Technology. Upholding Tsinghua University’s mission to “cultivate talents with a sound character of state and social services,” the DPIM always treats talent cultivation as its primary task, with the aim of cultivating outstanding “research, managerial, innovative, international” personnel in advanced manufacturing who master the trends of the times and pursue academic excellence.
Intern responsibilities: The IIP placement is within the Department of Precision Instruments and Mechanology and will focus on one of the following two projects:
1) Observation on the velocity profile of blood flow in microchannel using micro-PIV system-The motion of the red blood cells (RBC) in microvascular is strongly dependent on time, flow and geometries, and the microfluidics provide a good platform to study the blood flow in complex geometries. In this study, a T-junction microchannel is to be designed and fabricated based on soft lithograph technology, to observe the red blood cells (RBC) motion in the daughter branches. The velocity profiles of the blood flow is to be measured by the micro-PIV system using the RBCs as tracers, and the effect of the size ratio of the daughter branches on the motion of the RBCs is to be investigated.
2) Observation of the cavitation in a small glass venturi channel- The cavitating flow through a converging-diverging nozzle has important impacts on the engineering pipe flow and biomedical heart valves. To understand the cavitation of the liquid in small channels, a glass venturi shaped channel with the characteristic length of milllimeter is to be designed and fabricated. Using this device, the cavitation phenomenon is to be observed by a fast camera under the controlled driven pressures. Then the cavitation number and the effect of the liquid-solid interface are to be investigated.The IIP intern will participate in the experimental research related to microfluidic systems, and he/she will be responsible for the design and the proceeding of the experimental work.
Qualifications: This placement is ideal for candidates with interests in Mechanical Engineering, Fluid Dynamics, Bio Engineering, and Chemical Engineering. Experience and/or skills in technical drawing and common computer software, and basic experimental skills would be an asset.
Previous work responsibilities (in the words of a past IIP intern): Researched pulsatile flow and steady flow of red blood cells in a bifurcating microchannel and their clotting effects. This included designing the experimental setup, acquiring the necessary equipment and blood, fabricating microdevices, and running experiments.
