To ensure a safe and healthy environment within the tunnel, it is crucial to have a dependable ventilation system. This system will ensure a continuous supply of fresh air, minimizing the concentration of air pollutants during regular tunnel operations. Additionally, it will effectively extract smoke gases in case of emergencies. Utilizing Computational Fluid Dynamics (CFD) analysis for tunnel ventilation has become increasingly crucial in ensuring the safety, efficiency, and comfort of tunnel users. CFD analysis provides valuable insights into airflow patterns, temperature distribution, and pollutant dispersion within tunnels. Engineers can leverage these results to optimize ventilation strategies, such as adjusting fan placement or duct configurations, to enhance overall ventilation performance and user safety. By leveraging CFD simulations, stakeholders can make informed decisions that optimize airflow, minimize pollutants, and improve overall ventilation effectiveness. Our Computational Fluid Dynamics (CFD) simulation outcomes have allowed our client to comprehend the flow evolution within the entire tunnel and have faith in the suggested Jet fans and different operational configurations of motorized dampers for smoke extraction during emergencies. Our accurate HVAC CFD analysis results have empowered our client to make informed engineering choices for improved resource efficiency and safety adherence.

Agitators are equipment used to homogenize media inside a tank. They work by rotating immersed impellers at a controlled speed. The work exerted by the impeller induces the flow and shear of the media inside the tank, causing a single or multi-component media to homogenize. Agitators are used in industries to enable proper mixing of liquids, promote chemical reactions inside the equipment, keep homogeneous liquid bulk during storage, increase heat transfer during heating or cooling, disperse immiscible liquids, keep the product in a mixed state until used, blend miscible liquids, and dissolve some solids into liquid.

We carried out CFD analysis for the HVAC Jet Nozzle system proposed in the Wind turbine blade molding division at the LM wind power blade manufacturing plant in Bangalore. The blade manufacturing plant consists of four molding bays; for each bay, cold air will be supplied through 2 AHU units. Each AHU unit is connected to 40 Jet Nozzles. The main objective of this HVAC CFD analysis is to analyze airflow, air-impinging angle, and the flow regime. The flow regime plays a significant role from Health and safety perspective. We have explained our results to the Management of LM Wind power and recommended suggestions for Improvement.

RVBF is an Inert gas-circulated, closed-loop Integrated thermal system with operating temperatures up to 1500 Deg 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 of the job is essential to achieve the desired metallurgical structure after heat treatment. Niharika Computational Engineering Solutions Pvt Ltd (NCES) has collaborated with the client and analysed the overall thermal performance of RVBF.

Our Client TATA Elxsi has approached us to optimize the thermal design of the Automotive Power train controller unit. The client has come with dimensional constraints and inputs from the Electronics hardware team. We have guided the client starting from conceptual heat sink design, performed Computational Fluid Dynamics (CFD) analysis , fine-tuned the design with the help of CFD analysis results, and finally presented our part of the work to the Japanese end user. We have addressed heat dissipation, thermal contact resistance, and other input data uncertainties.

Closed loop anesthesia delivery systems are specifically engineered to automate and enhance the administration of anesthesia throughout surgical procedures. By constantly monitoring crucial indicators like oxygen levels and breathing patterns, these systems intelligently adapt the anesthesia dosage to ensure the patient receives the precise amount required at any given moment. This not only enhances the overall efficiency of the procedure but also significantly improves its safety.

The Remote Radio Unit considered for CFD analysis utilizes a passive cooling technique. The CAD design comprises various components such as the heat sink cover, power amplifier PCB, power amplifier PCB RF shield, power supply plus baseband PCB, power supply plus baseband PCB RF shield, SSG PCB, SSG PCB RF shield, cavity filter, and other mechanical housing. Total heat dissipation of the Remote Radio unit is about 600 Watts, with heat flux up to 35 W/cm2. All the heat dissipating components are modeled as 3D objects and volumetric heat load (W/m3) is imposed. Contact Resistance at the Junction is modeled as per the manufacturer provided resistance values.

Hypoxic ischemic encephalopathy (HIE) is a critical and potentially fatal condition that arises in infants as a result of inadequate oxygen supply and diminished blood circulation to the brain. Failure to promptly identify and address this condition can result in substantial neurological harm and enduring disabilities. In recent times, hypothermia therapy has emerged as a hopeful intervention for HIE, presenting the possibility of safeguarding the nervous system and enhancing the prognosis for affected newborns.
