Blood is considered as the human health repository due to the presence of various components that act as a biomarker and indicator. Human health information is easily available through blood component testing as each element exhibits different information about human health. The blood component separation is a crucial step to perform the blood component testing for disease diagnosis.

The size of a typical microfluidic device is 2 cm X 2 cm or smaller. Microfluidics lab-on-a-chip and point-of-care applications involve miniaturization of laboratory systems to accomplish tasks on-chip. We aim to develop sensors that can be integrated on-chip at the desired location for real-time measurement of fluid and flow parameters.

Impinging wall jets are effectively used in heat transfer applications such as cooling of turbine blades, electric motors, thermal management of battery systems, among others. Jet impingement cooling proves to be more efficient than other techniques in terms of providing a higher heat transfer rate and localised cooling at the hotspots. Since convective heat transfer is linked to the turbulent characteristics of the flow, any mechanism which can induce turbulence in the flow will influence the heat transfer rate.

There exist several operating conditions where gaseous flows behave in a counter-intuitive manner. One important and emerging application area that involves such a flow condition is the development of small scale or miniaturized devices. In such situations, the molecular separation (λ) becomes comparable with the passage dimension (D), which gives rise to a non-equilibrium condition of the fluid with the wall.

Advancements in micro- and nanomanufacturing using both conventional and non-conventional techniques (such as lithography, femtosecond lasers, electro-discharge texturing, and anodization) have significantly enhanced our understanding of surface texture interactions with external liquids across various applications. Lotus leaf-inspired superhydrophobic surfaces (SHS) have demonstrated exceptional success in liquid repellence, drag reduction, and anti-biofouling.

It is not always easy (and often not even possible) to solve partial differential equations analytically; therefore any new method to attack them is welcome. We have proposed a new iterative approach to obtain analytical solution of non-linear partial differential equations. The novelty is in combining physical situation to the mathematical process, during the solution procedure.

In recent years, piezoelectric-based energy harvesters have gained significant attention for capturing small-scale renewable energy from ambient flow sources. While conventional turbines are ineffective at low wind and water flow velocities, energy can be harvested at a smaller scale using flow-induced vibration-based piezoelectric transducers. Additionally, such harvesters are simple in design and easy to integrate into various systems.

Vortex induced vibrations (VIV) and Galloping are two instabilities which can be utilized to harvest energy. Such flow induced vibrations (FIV) can be utilized to harvest energy from the low speed flows where conventional hydro turbines fail as they require much larger velocity or potential head. The FIV system can be customized to harvest energy in specific velocity ranges as per the availability at the site.
