The microfluidic flows and mixing studies are becoming vital in the present era of miniaturization. The microfluidics-based biochips, also known as Lab-on-a-chip or bio-MEMS, are becoming increasingly popular for DNA analysis, clinical diagnotics and in the detection / manipulation of bio-molecules. Finding most suitable designs for these bio-MEMS is challenging and needs extensive research. At our laboratory, we study flow and mixing in the micro-devices by solving Navier-stokes equations using CFD Tools and computer codes.
The flow and mixing in the microscale is quite different from macroscale. Firstly the fluid flow in the microscale is affected by various other forces such as surface tension, electric forces (ex.: electroosmotic force) magnetic force etc. Secondly, due to the absence of convection currents and turbulent zones in the laminar micro flows, mixing is extremely slow as it depends on diffusion effect only.
This laboratory aims at
- Analyzing the influence of various forces, one by one on the fluid flow in micro devices using numerical simulation, so that the designer can predict the performance of the device prior to its fabrication.
- Enhancing mixing by introducing chaos and quantification of mixing quality(mixing index, Lyapunov exponent etc.).

Heat Laboratory 1 (RS223)
Our study is mainly concentrating on the development of cooling system. Especially, we have many concerns about the cooling issues on heat transfer of an electronic device. As electronic devices are getting smaller and functions to be required are getting complicated, heat release rate per unit area keeps being increased. As a result, cooling technology has been the important element in deciding marginal performance of electronic devices. Although the Heat Lab is currently at very early stage, it is developing a cooling system, which corresponds with current development stage of electronic technology, cooperating with other laboratories that are studying electronic packages.
