Abstract: In the present study the effects of oblique shock waves on the lateral diffusion coefficients of a 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) biological membranes through molecular dynamics simulations are being under examination. Computational simulations have been carried out by utilising the NPT ensemble with shock impulses varying from 0.33mPa s to 100mPa s. The applied incident angles vary between 0° and 80° corresponding to the perpendicular and almost tangential case respectively. It is shown that the membrane thickness gets thinner under the application of a shock. The area per lipid is also reduced, while the volume increases in the beginning of the application of the shock and afterwards it reduces until it gets to the same values that correspond to the equilibrium state.
Description: This paper was presented at the 3rd Micro and Nano Flows Conference (MNF2011), which was held at the Makedonia Palace Hotel, Thessaloniki in Greece. The conference was organised by Brunel University and supported by the Italian Union of Thermofluiddynamics, Aristotle University of Thessaloniki, University of Thessaly, IPEM, the Process Intensification Network, the Institution of Mechanical Engineers, the Heat Transfer Society, HEXAG - the Heat Exchange Action Group, and the Energy Institute.
