A CFD Analysis of the Air Flow Through the Stirling Engine’s Singularities

Houda Hachem, Ramla Gheith, Fethi Aloui, Sassi Ben Nasrallah, Meihong Wang

In this chapter, a computational fluid dynamics (CFD numerical model) of the air flow through a 300 cm3 Beta Stirling engine has been used to characterize the pressure drop and heat transfer through the regenerator. The Stirling engine had two moving parts (i.e. piston and displacer) which were at…

Combustion Analysis of Biofuel Derived from Waste Fish Fat

Edwin Geo Varuvel, Nadia Mrad, Mohand Tazerout, Fethi Aloui

Unlabelled - Drought is one of the major abiotic stresses affecting the maize production worldwide. As a cross-pollination crop, maize is sensitive to water stress at flowering stage. Drought at this stage leads to asynchronous development of male and female flower organ and increased interval…
