Training model to demonstrate the conversion of thermal energy into mechanical energy

Journal Title: Science and Education a New Dimension - Year 2017, Vol 0, Issue 128

Abstract

The article discusses the problem of familiarization of the students with physical basics of energy saving. Given the tech- nical description (design and operation of the proposed device for demonstrating the conversion of thermal energy into mechanical energy, determined by its position in the school demonstration experiment in physics and the peculiarities of its approbation. The proposed device for demonstrating the conversion of thermal energy into mechanical energy can be used in the educational process in physics as a visual demonstration tool in the study of selected topics in mechanics and molecular physics and thermodynamics. In this article the device in collaboration with the experimental group students obtained the patent of Ukraine for useful model “Device for demonstrating the conversion of thermal energy into mechanical energy”. The object of the invention was made by the use of previously known product (a child's toy “Protective boat”) for a new purpose – as a demonstration device for physical experiment. In contrast to known devices of similar purpose of use of the device in question allows you to demonstrate a closed cycle with a work- ing medium that experiences a phase transformation liquid-vapor-liquid; to demonstrate the use of converting thermal energy into mechanical energy for practical purposes; to be used as a source of energy for various fuels; to promote the safety demonstration of the transformation of thermal energy of the working fluid into kinetic energy of the model. A device and passed peer review on the national and international contests of physics and technical direction, where he received approval. The use of the model prorective engine expands the horizons of students in the field of energy saving (in particular, deepens their knowledge of the devices and methods of converting one form of energy into another), and also contributes to their interest in the study of physics as a whole.
