Background

Particulate Matter (PM) emissions has been one of main sources of air pollution. Many international cities suffers from air pollutions, eg. Beijing, New Delhi. It has been proved that PM2.5, PM10 has severe impacts on human healthy. And more specifically, ultra fine particles (diameter less than 1 micrometer) can penetrate blood vessel and deep into lungs leading to respiratory diseases. While enormous amount of PM emissions originates from traffic system, eg. particles discharged by tire-road abrasion which has being lacked of attention for a long time. And till now, it is still not clear how to visualize or predict PM emissions, eg. how particle size distribution looks like in a certain condition, how much tire-road abrasion is dischaged into air in the form of fine particle emissions.

Expected goals

• Clarify the equilibrium between tire-road abrasion and particle size distribution.

• Find a way to visualize or predict particle size distribution when the driving condition is determined, eg. building a mathematical / empirical model that can give a quantitative or qualitative description on PM emissions. Planned works

• Draft a schedule about your research.

• Do literature research and get to know how tire abrasion occurs, summarize the methods of researching on PM emissions.

• Gather useful data from literatures and find equilibrium between tire-road abrasion and PM emissions.

• Work out a method to visualize PM size distribution under certain driving condition.

• Validate the method with the data from internal drum test bench.

• Report the work weekly.

• Prepare thesis and presentation.

Requirements

• Major on Mechanical engineering and good at organizing / managing works.

• Familiar with programming platform, eg. Matlab.
