Essays on Thermodynamics

Science and engineering to a large extent live in separate worlds with their journals and conferences. It, therefore, took several years for thermodynamics to enter engineering circles. Well, in this article, ‘Current Trends in Finite-Time Thermodynamics,’ the author, Bjarne Andresen (a Professor of Physics at…

The review of the articles presents the characteristics of heat transfer in tube. Heat transfer of fluid and refrigerant flowing through a tube can occur in different types of thermal processes. Besides that, the design of tube can lead to other factors of heat transfer….

Cofficient Of Linear Expansionaim To determine by practical means within a laboratory environment, a value for the coefficient of linear expansion of a given material and compare the result with an accepted published value. The following apparatus were used to conduct the experiment. a. PASCO…

Forced Convection of air in horizontal tubes with conical inserts has been studied experimentally. The experiments are performed in turbulent regime. Different arrangement of conical ring have been employed for the experiments by different researchers. It was found that insertion of rings have significantly increased…

Solar still is a device which is used to obtain fresh drinkable water from saline water with the use of solar radiations and solar desalination process. There are number of solar still designs and various ways to increase its performance. So, in this review paper…

Polymer which is used tire cord manufacturing, is transferred with jacketed transfer line and heating box to provide thermal stability of the system after extrusion process. The heating box is heated with Dowtherm-A vapor to prevent heat loss from the polymer. In order to increase…

Types of Nanoparticles and Additives Zinc oxide (ZnO) is used as nanoparticle as additives in CIME. It is sent as nanofluid in various constituent level. Another additive used is Ethanox which is a good antioxidant. Various concentrations were added and tested. Biodiesel The biodiesel used…

INTRODUCTION Research into improvements of hot mix asphalt (HMA) materials, mix designs, and methods of pavement evaluation and design, including laboratory and field-testing can provide extended pavement life and significant cost saving in pavement maintenance and rehabilitation. Silicone rubber has been one of the most…

The results of computational analysis denoting the centerline velocity decay and the spreading rate of plane jets of air issuing into ambient air conditions are presented. The air flow is discharged from a circular inlet and through the gradual contour of the nozzle, it exits…

Based on the solid/fluid-coupling anisotropic idea, the BISQ theory was extended to the transversely isotropic two-phase case. Yang and Zhang proposed general elastic wave propagation equations based on the BISQ theory, and further expanded these equations to the viscous elastic medium. However, too many system-specific…

The thermal-hydraulic design of the microchannel heat sink A set of modeling simulations have been carried out in order to obtain the optimal thermal design of the heat sink by reducing the number of fins and simultaneously inserting pins inside channels. Basically, the pin size…

Aim of the study Heterologous and homologous protein secretion constitutes a field of great interest for the food industry. A little less than half of all the enzymes sold in a world-wide scale correspond to food and feed enzymes (Fernandes, 2010). Regardless of how potent…

Ethanol’s vapour pressure is lower than that of petrol, resulting in lower evaporative emissions while its flammability is also much lower than that of petrol, reducing the risk of vehicles catching fire. In addition, there is no gum formation associated with ethanol, and anti-oxidants and…
