Essays on Thermograph

Literature review

Heat transfer and friction characteristics in a square duct roughened by various shaped ribs on one wall [Aliaga, b, 1994]. Liquid crystal thermograph is used to measure local and average heat transfer coefficient of ribbed surface. The ribs height to duct hydraulic diameter ratio is fixed to 0.1. The rib pitch to height ratio varies from 8 to 15 and Reynolds number spans from 8000 to 20,000[Aliaga, b, 1994]. The experiment consists of heat transfer test and pressure test. The test experiment consists of 750mm long smooth duct followed by a rib-roughened section of equal length. Plexiglas plates are applied to ...

Introduction and Literature Review

The value for a drug is significantly impacted by the dissolution rate, chemical stability and solubility of the drugs thereby impacting the pharmaceuticals efficiency as well. In the pharmaceutical industry multi-component crystals such as hydrates, solvates, co-crystals and salts have a major role during the design of new solids. Solid does not self-crystallize. It crystallizes in varied forms depicting random crystal properties. Various approaches are used to modify solids like Salting, Solvation, Hydration, and Polymorphism. Apart from these approaches, Co-Crystallization is a promising new approach to modifying solids (Nauha, ...
