Heat transfer augmentation by using different techniques in heat sinks: A review study

Abstract

The current paper reports the major trends in scientific research that occurred recently in the field of removing generated heat in electronic equipments using passive majorly and active minorly. The studies in literature are distributed between many sub-categories like: changing the geometry of extended surfaces, or the material that manufactured from, the working fluid that passed over them and / or the dimension of channel whether mini or micro.

Bioethanol Production From Agricultural Waste: A Review

“…The world is confronted with an important challenge arising from the rise in population growth and at the same time the escalating demand for energy sources. This urgent issue revolves around the necessity to fulfill energy deficiencies for transportation, heating, and industrial processes [1], taking into account the necessity of addressing environmental pollution and limiting global warming and climate changes, where gas emissions resulting from the use of fossil fuels are among the most prominent its sources [2], For these reasons, biofuel production is one of the ideal energy sources that contribute to meeting needs and achieving development sustainable [3]. Biofuel is any fuel produced from biomass, whether solid, liquid, or gas, and is considered a biofuel.…”
