<br/><br/> In inertial Microfluidic field, movement of different particle causes different equilibrium<br/>position in microchannel because of the inertial effects. For particle sorting this is not appreciable.<br/>So with the help of secondary flow (which is at right angle to the primary flow) and drag of<br/>particles, number of equilibrium positions can be reduced and this also help in focusing of the<br/>particles. Amplitude and direction of secondary flow can be influenced by the curved configuration<br/>of the microchannel. In this thesis work, three different size of blood cells (Erythrocyte 9µm,<br/>Lymphocyte 15µm and Monocyte 20µm) were analyzed using passive techniques. We used two<br/>different techniques for the manufacturing of microchannel. First microchannel was produced by<br/>using SLA 3D printing and second channel was manufacture by using laser cutting technique. In<br/>both techniques, there was only one inlet and three outlets. We use three different angles (30, 60<br/>and 90) between outlets for each manufacturing technique. Both channels were studied under<br/>microscope. Among these two channels laser channel gives better results. After taking images with<br/>the help of microscope, image post processing was done by using MATLAB. We can use that<br/>microfluidic device in medical labs as it is easy to use, portable and had low cost.
