Transient thermal analysis of different types of IC engine cylinder fins by varying thickness and introducing slots
Fins are extended surfaces used between two fluids for heat transfer between the hotter and colder fluid or between a solid and a fluid. There are various types of fins, viz. angular fins, circular fins, and rectangular fins. Engine piston chamber is the most precarious part of any automobile imperiled to extreme thermal shocks, hence prone to thermal stresses. Therefore, fins are introduced to cool the cylinder, which...
Thermal deformation of a thermal shield material vs. method of heat supply
This work aims to analyze the thermal deformation of a thermal shield laminated material under a uniform or one-sided heating of up to 600°C/min. The material is made of a fiberglass composite polymer material based on phenol-phormaldehyde matrix. This work describes the method used to study the kinetics of thermal deformation of the composite material at different heating rates and a high-temperature of gas flow...
Physics of deactivation of gyroscopic inertial forces
This new study on effects of gyroscope demonstrates the action on the spinning disc that the eight interrelated inertial torques system generated by its rotating masses. The physics behind this inertial torques manifest the action of the resistance and precession torques, which physics are described and explained. The latest research on the gyroscopic properties revealed the deactivation of the inertial torques that...
Development of a mathematical model to study the impact of state of charge dependent exchange current density on the generated voltage hysteresis of silicon anode-based lithium half cells
In this work, three different types of Silicon (porous, nano and bulk) anode-based coin cells are manufactured and lithiation-delithiation battery cycling tests are conducted. During the experiment, a capacity difference is witnessed at the beginning and the end point of the battery cycling loop. This capacity difference during battery cycling is reduced by implementing side-reaction correction technique on the exchange...
