CFD analysis and coolant flow optimization for neonatal body temperature controller unit
Neonatal body temperature controller is an initiative of the Government of India to save the lives of newly born babies from Hypoxic ischemic encephalopathy, a type of brain dysfunction resulting from impaired cerebral blood flow and oxygen delivery to the brain.
Immediate treatment for this condition involves cooling the brain and whole body of the infant to just a few degrees below average body temperature soon after birth, for three days with close medical supervision, and slowly rewarmed back to moderate body temperature.
Cooling is achieved by wrapping the baby in a cooling blanket circulated with the thermally controlled water-glycol medium.
Niharika Computational Engineering Solutions has collaborated with the client in all stages of the product development cycle of the cooling blanket.
Computational Fluid Dynamics (CFD) analysis technology is extensively used to analyze the fluid circulation in the blanket.
Our strong fundamentals in theoretical fluid dynamics leveraged with computational fluid dynamics solver have enabled us to optimize the design for uniform circulation of fluid in the blanket, which in turn ensures consistent body temperature of the neonates. Niharika Computational Engineering Solutions, applying technology precisely for a better tomorrow.

CFD analysis of closed-loop anesthesia delivery system (CLADS)
We collaborated with Skanray Technologies, one of the foremost global medical device market players, to analyze the fluid flow in a closed-loop anesthesia delivery system.
The prescribed limit for pressure losses in the closed loop anesthesia delivery system is around four centi meter water column (392 pascals). This calls for meticulously crafted CFD analysis practices.
We employed the most accurate boundary layer modeling approach in our CFD simulations. The turbulent boundary layer was resolved right from the beginning of the viscous sub-layer. We adopted precise verification steps in every stage of CFD analysis to deliver accurate results.
Our team exhibited a high level of flexibility and worked closely with the R&D team of Skanray Technologies. In the end, we obtained the best correlation of results, having perfect behavior of test results with the CFD model.

CFD analysis of Rotary Vacuum Brazing Furnace (RVBF)
Liquid Propulsion Systems Centre, the propulsion complex of the Indian Space Research Organization, has established a Rotary Vacuum Brazing Furnace (RVBF) for the metallurgical treatment of cryogenic rocket propulsion systems.
RVBF is an Inert gas-circulated, closed-loop Integrated thermal system with operating temperatures up to 1500 degrees Celsius. The Integrated thermal loop consists of a heat treatment chamber, a centrifugal blower for gas circulation, Shell and Tube Heat exchanger to achieve gas cooling, and an Electromagnetic Induction heater to reach a higher operating temperature.
Controlled cooling is essential to achieve the desired metallurgical structure after heat treatment.
We worked closely with all the agencies involved in this turnkey project and conducted the necessary Computational Fluid Dynamics (CFD) analysis to assess the thermal performance of the Integrated RVBF unit.
We validated our CFD analysis model with the test results conducted on an already existing RVBF unit of slightly lower capacity. Our CFD analysis results are 90 % close to measured values.
