Mathematical models  to describe the thermal parameters of the solar cooking and TES system are developed  using energy balance equations. The models are validated with experimental data and  reasonable agreement between experiment and model is achieved. Two charging methods  of the TES system are proposed and implemented using a Simulink block model in the  Matlab environment.The constant flow rate (CFC) method charges the storage at a  constant flow rate while the constant temperature charging (CTC) method maintains the  outlet charging temperature at a constant value by making the flow rate variable. Simulation  results indicate a greater degree of thermal stratification, a greater energy stored  and a greater exergy stored when using constant temperature charging.The performance  of three solid material (fused silica glass, alumina, stainless steel) for the pebbles is simulated  and compared in terms of the axial temperature distribution, the energy stored  and the exergy stored.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659364105\"\u003e\u003ch3\u003eA Research work submitted to the North West University in South Africa for the degree of Doctor of Philosophy in Physics\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783659364105","offer_id":39485425713245,"sku":"9783659364105","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/ef00730a-ed27-44a5-83c8-47e1a2f8675b.jpg?v=1765086886","url":"https:\/\/shop.autorenwelt.de\/products\/characterisation-of-a-thermal-energy-storage-system-von-ashmore-mawire","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
