Time dependent mathematical model of air pollutants emitted from time-dependent elevated line source into a stable atmospheric boundary layer
A time dependent atmospheric model is represented for chemically reactive primary pollutants emitted from an elevated line source into a stable atmospheric boundary layer, over rough surface terrains. The time dependent model was obtained through an analytical solution from a multiple Inverse Laplace transform of the atmospheric diffusion equation with the parabolic eddy-diffusion coefficient (exchange coefficient) and...
Inter-provincial cooperative control of air pollution in China
Based on the status of the air pollution in China, three basic assumptions are proposed. The China’s inter-provincial cooperative control of air pollution (ICCAP) model is established by the combination of national optimization model and allocation model of cooperation benefit. A case study for the pollutant SO2 control in China shows that the proposed model is superior to the current command-order regulation. Our...
Extreme pressure property of Carbon Nano Tubes (CNT) based nanolubricant
The paper predicts the exceptional extreme pressure properties of multi walled carbon nano tube as compared with traditional mineral oil which also contained some additives and graphite. The extreme pressure property was predicted by four ball tester. In the test the load bearing capacity of the newly developed nano oil was predicted to have a better value than the commercial available mineral oil. The weld load of the...
