Abstract:
Objective To investigate the transportation of chemico-biological particles(CBP) through the micropassage inside the human body in order to improve chemico-biological protection.Methods Dissipative particle dynamics (DPD) method was used to study CBP transportation through micropassages inside the human body.Results The Poiseuille flow could be ensured by imposing boundary conditions including pressure gradient and no-slip.The axial velocity between fluid particles and CBPs was well matched except the area close to the passage wall.However, CBPs tended to accumulate and the density of CBPs slightly increased, leading to the jam effect and producing particle accumulation.Conclusion The characteristic of CBP transportation is better understood,which can help develop some chemico-biological protection devices according to movement of CBPs and improve the performance of CBPs during chemico-biological protection.
