Acoustics & Aero-Acoustics

Acoustics has become a important design criteria in product development due to increasing stringent standards and comfort level has been a marketing argument. There is Increasing need for acoustic simulation due to the fact that prototyping is costly and acoustic testing are difficult to perform. Simnxt Solutions offers State-of-the-Art Noise Source computation with either steady RANS with  SNGR approach  or unsteady CFD simulation and  acoustics propagation using a hybrid Computational aero acoustic method. Experience in  tonal noise of prediction of Turbo machinery and broadband noise generated by the turbulent flow.


 

 

Combustion Analysis

Over 90% of energy conversion processes are based on combustion. Since combustion is the integral part of various engineering applications IC Engines, Gas Turbines, Rocket engines, Furnaces and power generations,       Combustion modelling plays a major role during the design , analysis and Performance. Simnxt Solutions developed a methodologies for Turbulent combustion which involves fast chemistry, non-premixed combustion, premixed and partially premixed combustions. Simnxt Solutions offers a wide range of combustion solutions for Gas Turbine Industries, Automotive Industries & Process Industries. Our team has strong experience in Combustion physics including surface chemistry pollutant modelling and radiation modelling.


External Aerodynamics

Most of the Industrial external aerodynamic flows are turbulent and essentially non-linear. The disparity of scales are extremely changing.  Simnxt Solutions offers wide range of external aerodynamic solutions in steady-state and transient aerodynamics of HVAC systems, vehicles, aircraft, helicopter, airplane, plane, flight buildings, structures and wings. We are well versed in computational fluid dynamics methods, modeling & simulation from linear potential panel methods to one and two equation turbulent Reynolds number averaged Navier-Stokes methods. We are well versed in aircraft performance calculations differentiating flight manual performance from operational performance.


 

 

Electronics Thermal Management

In past few years, advancements in the electronics products has become compact and thereby having high density components producing high heat in electronic system. The operating temperatures of the component is very important to prevent it from failing. The air flow path and temperature distribution helps in the studying the recirculation areas and right selection of materials to dissipate the heat from the components. The placements and sizing of the fans , vents and placements of the thermal cooling devices as thermal pads, heat pipes & Thermal electric coolers. Simnxt Solutions helps the electronics design engineers to decide the design based on the following analysis such as Board level analysis & system level analysis.


Data Center Modeling

Cold air movement inside a data center provides us a detail study of re-circulation region and hot spots of the equipment's where it receives the less amount of air. Data center analysis helps in providing the optimized design, cost saving, prevents over heating & increases performance. Examining hot/cold aisle arrangements , placement of blanking panels, closed containment regions to avoid improper mixing of cold air with hot air. Pressure distributions in raised floor, data center region & false ceiling are studied. Rack inlet and exhaust temperatures, CRAC set temperatures & return air temperature are cross checked with the hand calculations.


 

 

Turbo Machineries

Turbo machinery is essential component  in the most of the engines and also a standalone machine for energy generation. Computational fluid dynamics (CFD) probably plays a greater part in the aerodynamic design of turbo machinery than it does in any other engineering application. Design of a modern turbine or compressor has been unthinkable without the help of CFD. Simnxt Solutions offers high fidelity simulation technique for designing and improving the performance of Turbo machinery (i.e Compressor , Fan , Wind turbine). High level technical expertise in steady (mixing plane, frozen rotor ) and transient simulations of rotor-stator interaction effects and large unsteady separations simulation to provide physical insight of the Turbo machinery design.


Thermal Comfort Modeling

In the past few years, Computational Fluid Dynamics is playing a vital role in the external and internal building design. CFD helps the designers to build efficient and effective designs to provide safe and comfortable areas. CFD is used to assess the design is meeting the ASHARE standards of indoor air quality in the buildings. The uniform distribution of the air temperature, velocity and humidity are the important parameters that govern the comfort factors in indoor building simulation. Simnxt Solutions is actively working with various projects related to Atriums, Airports, Amphitheatres, Clean room environments, Gymnasiums, Hospitals, Indoor stadiums,  Machine shops and Laboratories.


 

 

Heat Transfer Analysis

Heat transfer has broad application to the functioning of numerous devices and systems such as automotive engineering, thermal management of electronic devices and systems, climate control, insulation, material processing and power station engineering. Heat-transfer principles may be used to preserve, increase, or decrease temperature in a wide variety of circumstances. Our CFD analysts can simulate most complex heat physics such as conduction, convection, radiation, conjugate heat transfer, environmental heating, phase change and many others. Team has strong experience in Heat Transfer physics such as Natural Convection, Radiation Modelling, Fluid Structure Interaction etc.,


Toxic Gas Contaminant Analysis

Indoor air quality are essential to ensure that the required air quality standards are complied. Clean room environment simulation helps in simulating the accidental introduction of the hazardous materials. The concentration and the distribution in the room is determined for the various range of operating conditions. Car park ventilation simulation helps in determining the distribution of CO levels in the basement and the effective displacement of CO Containment using the ventilating devices. Providing the optimized designs such as placement of the ventilating devices in order to meet the Indoor air quality standards.


Fire & Smoke Simulations

In any fire accidents, the evacuation of the smoke and heat from the fire accidental areas becomes a tougher task in enclosed and open spaces. Fire simulation helps in simulating the smoke propagation from the burning material. CFD Fire simulation helps engineers to design the building in fire safety aspects such as visibility and temperature over a period of time. Fire simulation provides the various parameters such as fire intensity, flame height & materials subjected to fire. Simnxt Solutions is currently providing the solutions to various buildings such as atrium's, tunnels, shopping malls, etc.,


1D CFD Analysis

1D CFD Analysis is used to analyse fluid systems like hydraulic systems, pneumatic systems, exhaust systems, cooling systems etc.,. 1D CFD Analysis helps in faster design process, improved product design, less rework, improved quality, reduced prototypes, faster time to production. It is used to model flow rates, pressure changes and temperature fluctuations in 1D fluid systems. The network of pipes, connectors, valves, pumps, compressors, heat exchangers and other similar components are made used to build networks of the system which are commonly found in automotive, aerospace, oil& gas, power and energy industries.
