PROJECT DETAILS
CVI and CVD is a thermo-vacuum chamber operating up to 2500 Degree Celsius. CVI-CVD furnace is mainly to mold high-temperature sustainable composites used in supersonic missiles. This Thermo-vacuum facility is commissioned at DRDL- Hyderabad, the Defence Research and Development Organization (DRDO) propulsion complex, Ministry of Defence, Government of India. The electromagnetic Induction heater is used to generate higher operating temperatures of the order of 2500 Degree Celsius. Niharika Computational Engineering Solutions Pvt Ltd (NCES) has collaborated with the client and conducted Computational Fluid Dynamics (CFD) analysis to assess the thermal performance of the furnace. We also conducted structural analysis (FEA) to predict the thermal expansion of the plunger unit.

CFD analysis of Rotary Vacuum Brazing Furnace (RVBF)
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 analyzed the overall thermal performance of RVBF. We conducted transient Computational Fluid Dynamics (CFD) analysis to analyze the cooling of the job during the cooling cycle. Our CFD analysis process is validated with the help of experimental data obtained from the existing RVBF unit, which is of slightly lower capacity. Read More
Thermal analysis of Landing gear magnetic brake disk
Magnetic brake is a direct replacement for the current state-of-the-art carbon brakes. The magnetic brake can recapture a significant portion of the aircrafts kinetic energy during the landing. In this project, we carried out CFD analysis for the aircraft landing brake for a range of decelerating speeds. Our scope of work is to calculate the heat dissipation during the landing of the aircraft and conduct thermal analysis to estimate the temperature developed on the critical components of the braking system, which further helps the designer choose a suitable cooling mechanism. Hexahedral mesh is generated for the CFD domain, and CFD analysis is carried out using the Multiple Reference Frame Model (MRF). Read More
