Abstract
Recently, architecture design has combined the concept of the biological architecture and organic architecture by imitating the function type from the nature world. This paper discusses the correlation between the morphology parameters of intertidal snail shells and their heat-transfer coefficients during the heating and cooling experiments. According to the result, we take the parameters to design architecture and create a comfortable heat condition in the interior.
This study focuses on four species of intertidal snail which are not rare in Taiwan(Omphalius nigerrima, Clypeomorus humilis, Cerithidea rhizophorarum, Littoraria scabra). There are much difference to the morphology, surface and the specific heat among these shells, and it reflects the evolution of the morphology for resisting the impact of the habitats which distribute over the different vertical sections of the shore. As the result of the heating experiment, Omphalius nigerrima has the highest heat-transfer coefficient, 3.33±1.01×10-3 WK-1cm-2,and Littoraria scabra has the lowest one, 0.60±0.04×10-3WK-1cm-2. During the cooling experiment, Clypeomorus humilis has the highest heat-transfer coefficient, 2.64±0.51×10-3 WK-1cm-2, and Littoraria scabra has the lowest one, 0.60±0.04×10-3WK-1cm-2. It has the highest heat-transfer coefficient when the shell tip is against the wind in the wind field. Density and material volume are the most significant parameters of the correlation between the morphology and heat-transfer coefficients. Therefore, the heat-transfer of the shells is mainly effected by the conductivity. The specific value of surface area and overall volume are more significant to heat-transfer than the length-width ratio in the wind field. In other words, the morphology complexity of the shells has greater impact than the shell structure.
The morphology parameters of the snail shells can be applied to design office building, storehouse, basketball court, recreational architecture, platform and its accessory equipment, in order to create a suitable heat condition .
