The CTURA SE-1 project required a precise temperature of 700 deg Celsius. A heating chamber/kiln was developed which required the development of a meta-model for temperature-voltage relation since it is micro-controller controlled. The process involved data gathering process which required us experimenting with an already developed heating furnace.
This project was motivated from CTURA SE-1 Project. The functional analysis of the prototype stirling engine required a heating system. CTURA team researched, designed and developed the system. The system’s was such that temperature settings to a high precision is required. CTURA team carried out experiments in order that effective meta-model which provides the effective temperature reading was modeled. All this was done for effective control. The design of the insulation system involved finite element modeling, to ensure that the materials can withstand the temperature requirements.
Also, the contracted fabricated parts which includes the mold, were done under the supervision of CTURA team.
The CTURA SE-1 Stirling engine project was motivated out of the power challenges in certain part of the world. And Also, the need for clean, renewable energy sources. The objective is to produce power of 1.5KW for water pump. The project has been the hallmark of CTURA Solutions thus far. And the design and development process has being very fascinating, with lots of learning along the process.
The preliminary design process involved lots of simulations and computations to obtain the required parameters. The prototyping was such that CTURA team was at the forefront of every activity. The project was the source of the heating chamber/kiln project.
To gain insight into the behaviour of the system, thermal analysis was conducted on a component of the stirling engine using computer simulation such as Elmer finite element modeler. Our high performance computers were able to produce timely effective results from small discrete elements. A multiphysics analysis involving thermal and mechanical analysis was also conducted to ensure the device meets the necessary requirements. CTURA also utilizes other FEM softwares such as Abaqus, Ansys
This preliminary 3D printed small scale model is part of the CTURA PSC-1 project. The objective of this 3D printed model was to test the functionality and tracking capability of the developed tracking system. The result of the prototyping was fascinating.
The small scale collector was stable and rotated effectively, tracking a point light source movement. This model, gave us confidence in proceeding into the next phase of the design process.
After much research, computations and iterations, a rhombic drive mechanism for the CTURA SE-1 Stirling Engine was selected, modeled and animated
