Abstract

Heat transfer through a cylindrical pin fin s studied. For the purposes of this study, thermal conductivity, heat transfer coefficient and the source terms and the sink terms are assumed to depend on the temperature. In the model being used for the study, the source and sink terms are given as arbitrary functions. We therefore employ techniques on symmetry to find the forms of the source and the sink terms which the extra lie point symmetries are admitted. The method of separating variables is used in the study to get the exact solutions when the equation for the equation is ...

- Load sensing control in hydraulics
Load sensing describes a pump control system that is used in open circuits. The control mechanism involves two steps. First, the load coming downstream induces a pressure on an orifice. The load pressure is sensed and determined. Secondly, the load pressure is adjusted in order to ensure a constant pressure drop, thereby enhancing a constant flow athwart the orifice. In load sensing control, the pressure that is induced by the load is fed through the load signal gallery into the pump. Due to the increase in the load pressure, the load sensing controller increases the pump ...

- Introduction
Thesis: The main steps in the process of heating water using solar thermal panel are (1) trapping the sun’s energy, (2) Heating water, (3) Storing hot water, and (4) Distributing hot water to points of use.
- Trapping sun (solar) energy
Solar thermal panel is a system designed for heating water using free heat from the sun. It converts sunlight directly into heat making converted heat available for different applications. Various factors affect the amount of solar energy collected in a panel. These are geographical location, season, time of the day, local weather and local ...
