| Abstract | In order to improve the complicated fabrication process and integration of 3D micromixers, we propose a novel planar self-stirring micromixer with high mixing efficiency and low pressure drop. The planar micromixer with vortices agitation for mixing enhancement had been successfully investigated by the Taguchi method, CFD-ACE simulations and experiments. The factor sensitivity test was performed by L9(34) orthogonal array in Taguchi method. Degree of sensitivity ranks as: Gap ratio > Number of mixing units > Baffle width > Chamber ratio. At Re = 20, micromixer shows 93% mixing efficiency in the adaptive design with three mixing units, H/W = 1/8, $W_{m}/W$ = 1 and $W_{m}$ = 80. The corresponding pressure drop of this adaptive design is only 4600 Pa at Re 20. Much improved mixing is obtained experimentally in this adaptive design at Re 20. The results of the factor sensitivity test can provide useful information for the design of the micromixers with obstacles. Merits of this design are easy fabrication and high integration capability. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
