ABSTRACT:

			
				
					
						The skin patterns of fast swimming sharks present varying configurations of interlocking
microscopic scales, for the permission of increased efficiency between the interaction of the
sharks surface and the surrounding fluid. These patterns have been deemed to follow riblet
structured configurations by multiple past researchers, with representative surfaces investigated
in their individual emanation of specific shark skin properties, for the accumulative reduction of
surface friction resistance. Previously publicised research has recorded a notable reduction of
surface friction resistance in the region of 10%, through optimisation of the particular structures
geometrical attributes, highlighting the desire for application within the commercial sector. These
studies have considered varying aspects of any riblet structures influence on drag reduction,
however, they present multiple evaluations between the justification of any reduction and the
instigation of fundamental characteristics within the fluid flow. In order to clarify the balance of
characteristics required for presentation of any reduction in surface friction resistance, this study
explores the simulation of three riblet structured configurations by computational fluid dynamics
analysis, whereby, the endorsed drag influences of each case are evaluated in respect to their
resultant fluid flow properties. In conclusion of this process, a conquering geometrical
configuration is then apparent, allowing further investigation of the particular structure towards
application on a representative submarine hydroplane to commence. This secondary area of
investigation is presented in attempt to relay the findings of simplistic riblet application towards
realistic structures. Although the evidential restraints enforced on the final simulation prohibit
any reduction in surface friction resistance to be taken from this analysis, this area of subsidiary
investigation nonetheless contributes value towards the advancement of future shark skin study,
where a perceived shift in focus is destined towards their investigation on ‘real life’ bodies.
