system is presented‚ then the system was designed‚ analyzed and optimized. There are many types of heat losses in the dish/Stirling system‚ such as convection and conduction heat losses and radiation heat losses by emission in the cavity receiver and reflection heat loss of solar energy in the parabolic dish. There are also internal and external conduction heat losses‚ energy dissipation by pressure drops and energy losses by shuttle effect in displacer piston in the Stirling engine. All of these heat

Unit 1 This scheme of work suggests possible teaching and learning activities for each section of the specification. There are far more activities suggested than it would be possible to teach. It is intended that teachers should select activities appropriate to their candidates and the curriculum time available. The first two columns summarise the specification references‚ whilst the Learning Outcomes indicate what most candidates should be able to achieve after the work is completed. The Resources

There are four avenues of heat loss: convection‚ conduction‚ radiation‚ and evaporation (Wikipedia‚ 2012). If skin temperature is greater than that of the surroundings‚ the body can lose heat by radiation and conduction. But if

P1 AQA – Revision Notes 1. Heat Transfer • Thermal radiation = infra-red radiation (beyond red part of visible spectrum) • Surface of sun is 5500 degrees. • Greenhouse effect is the idea that the earth is a greenhouse‚ and the atmosphere is glass that stops substances exiting or entering. • DARK‚ MATT SURFACES emit more radiation than shiny‚ light ones‚ and absorb radiation better. • Conduction: free electrons are given energy where heated and diffuse – this energy is passed on as electrons
