Over the last decade, computational methods have been intensively.applied to a variety.of scientific researches and engineering designs. Although the computational fluid dy.amics （CFD） method has play.d a dominant role in study.ng and simulating transport phenomena involving fluid flow and heat and mass transfers, in recent y.ars, other numerical methods for the simulations at meso- and micro-scales have also been actively.applied to solve the phy.ics of complex flow and fluid-interface interactions. This paper presents a review of recent advances in multi-scale computational simulation of biomimetics related fluid flow problems. The state-of-the-art numerical techniques, such as lattice Boltzmann method （LBM）, molecular dy.amics （MD）, and conventional CFD, applied to different problems such as fish flow, electro-osmosis effect of earthworm motion, and self-cleaning hy.rophobic surface, and the numerical approaches are introduced. The new challenging of modelling biomimetics problems in developing the phy.ical conditions of self-clean hy.rophobic surfaces is discussed.

In the present research, a bubble dy.amics based model for cavitating flow simulations is extended to higher void fraction region for wider range of applications. The present bubble model is based on the so-called Ray.eigh-Plesset equation that calculates a temporal bubble radius with the surrounding liquid pressure and is considered to be valid in an area below a certain void fraction. The solution algorithm is modified so that the Ray.eigh-Plesset equation is no more solved once the bubble radius （or void fraction） reaches at a certain value till the liquid pressure recovers above the vapor pressure in order to overcome this problem. This procedure is expected to stabilize the numerical calculation. The results of simple two-dimensional flow field are presented compared with the existing bubble model.

Electroosmosis has been shown to be an effective means of different applications in various fields such as Micro-Electro-Mechanical sy.tems （MEMS） and biomimetics applications. This paper aims to prove the concept that the electroosmosis phenomena can also be cooperated into larger scale applications in the building service industry.like dehumidification or damping proof. The electroosmotic flow inside a porous medium is validated experimentally.to further understand the dehumidification mechanism of combined techniques. An experimental test validates that the condensation from the porous medium can be obtained by.electroosmotic force generated by.external electric field, especially.for specific desiccant powders like zeolite and diatomaceous earth. With a range of volts from 5 V to 20 V apply.ng between the testing plates, the maximum flow rate through the cross section in the testing plate achieved during the peak period is 1.35 laL＇min 1. These promising phenomena can act as an alternative way.for energy.choice in dehumidification industrial field. Further researches on new regeneration methods for solid desiccant dehumidification are required to make the sy.tem simple, energy.saving and suitable for small air conditioning units.

The mechanism of tensile deformation in semi-cry.talline poly.ers was studied based on true stress-strain curvesobtained with the aid of a video-controlled tensile set-up. The deformation is affected by.both the cry.talline and theamorphous phases. However, the relative weights of the two portions change with the deformation stage. At lowdeformations the coupling and coarse slips of the cry.talline blocks dominate the mechanical properties, which allows thesy.tem to maintain a homogeneous strain distribution in the sample. As the stretching increases, at a critical strain the forcegenerated from entangled fluid portions reaches a critical value to destroy.the cry.tallites. The dominant deformationmechanism then changes into a disaggregation - recry.tallization process.

The possibility.of using Neumann＇s method to solve the boundary.problems for thin elastic shells is studied. The variational statement of the static problems for the shells allows for a problem examination within the distribution space. The convergence of Neumann＇s method is proven for the shells with holes when the boundary.of the domain is not completely.fixed. The numerical implementation of Neumann＇s method normally.requires significant time before any.reliable results can be achieved. This paper suggests a way.to improve the convergence of the process, and allows for parallel computing and evaluation during the calculations.
