Simgrosys provides services in aerodynamics of automotive vehicles such as cars and trucks. It has already executed number of projects in the design and development of add-on aerodynamic structure for tractor-trailers. The structure developed by Simgrosys was able to reduce the drag by 25% and increase the fuel efficiency by 4%. The aerodynamics deals with the flow of gases (especially air) over bodies such as aircraft, rockets, and automobiles at high or low speeds. Understanding motion of air around an object enables the calculation of forces and moments acting on the object. Typical properties calculated for a flow field include velocity, pressure, density and temperature as a function of spatial position and time. Aerodynamics allows the definition and solution of equations for the conservation of mass, momentum, and energy in air. Simgrosys supports aerodynamics design of automotive body shapes through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer simulations.
Simgrosys consists of experts who can perform external aerodynamics study of flow around solid objects of various shapes. Evaluating the lift and drag on an airplane or the shock waves that form in front of the nose of a rocket are examples of external aerodynamics. Simgrosys also performs internal aerodynamics study of flow through passages in solid objects. For instance, internal aerodynamics encompasses the study of the airflow through a jet engine or through an air conditioning pipe. We solve the problems at subsonic, transonic, hypersonic at different speed conditions.
Simgrosys provides services in thermal management of automotive under hood and under body. Having equipped with higher end hardware, Simgrosys can deliver the results design changes made in under hood or body in very less time. Thermal design engineers here will solve the design issues related with radiators, intercoolers, condensers, fans within a shorter lead time as they are facing number of similar challenges each and every day. They use various CAD, FEA, CFD and Multi body dynamics packages to solve the problem very quickly.
Generally, oil pumps are used for pumping lubricating oil into engine parts which will become hot while running at high speeds. Lubricating oil pumping mechanism is one of the critical members in a engine system which consists of components such as oil pump, inlet pick-up tube, strainer, pressure relief valve, and inlet and outlet ports.
The performance of a lubrication system is mainly controlled by the overall efficiency of oil pump along with its inlet and outlet components. Very recently, gerotor (generated rotor) pump - an internal rotary positive displacement pump started to replace other members of the group of positive displacement pumps due to its higher volumetric efficiency, smooth pumping action and ability to handle a wide range of fluid viscosities.

Key differentiators of Simgrosys engine cooling services:
HVAC duct designers in Simgrosys are having more experience and expertise in conceptual design through preliminary to final design of automotive cabin ducts to achieve target air flow. All these design phase are driven and enhanced by FEA and CFD simulation processes. They design
HVAC engineers in Simgrosys have more knowledge and exposure in the European and USA Federal automotive regulations and they design the HVAC systems of automotive vehicles cabin accordingly. They also perform FEA/CFD simulations for evaluating their design is compliance with prescribed regulations. In Simgrosys, lot of such simulations was carried out to validate the HVAC design. For example, a detailed defrosting and deicing study was carried out to validate the design, as per EEC 317 regulations. These simulations results are compared with test results and the correlation was found to be good.Heater Cores / Heat Exchangers / Fans
Simgrosys will help for designing all kind of heat exchangers such as radiators, condensers, intercoolers. We make hand design calculations, 2D and 3D drawings, FEA validation for thermal deformation, and CFD for pressure drop prediction and heat transfer happened in heat exchangers. Our engineers also deal with the design of heater cores. They will decide the number of tubes, ways to improve the heat transfer area using various techniques such as iterative, simulation, thermal calculations. Simgrosys designs fans. Based on the customer requirements, the blade profiles are designed and optimized to reach the target mass flow rate. The aerodynamics of fan shroud are also formulated and validated by our engineers. CFD simulations are conducted to enhance the design process and physical testing also carried out to confirm. Our well talented acoustic team works for noise monitoring and control techniques.
