Enigmas (Puzzles) in Teaching and Learning of Physics
Abstract: Teaching and learning of physics has been considered a challenge by both the teachers and students in India. The text books prescribed normally do not refer to these challenges which are mostly at conceptual level. An attempt has been made to recall some of the puzzles which are encountered by most of the students in learning physics. The historical origin of puzzles in particle physics has been brought into focus …

Exergetic Analysis of Single Effect LiBr-Water Absorption Cooling System
Abstract: Abstract This paper presents the exergy analysis of single effect LiBr-Water absorption cooling system. The work is committed to the study, the evaluation and distribution of the destroyed exergy for each component constituting this kind of system. The thermodynamic models, derived using the first and second laws of thermodynamics, are employed in a computer program using the engineering equation solver (EES) software to perform the calculations. Influence of various operating …

Energy and Exergy Analysis of Boiler and Turbine for Thermal Power Plant: A Review
Abstract: This paper presents thermodynamic analysis of boiler and turbine. Most of the power plants are designed by the energetic performance criteria based on first law of thermodynamics only. The real useful energy loss cannot be justified by the first law of thermodynamics, because it does not differentiate between the quality and quantity of energy. Energy analysis presents only quantities results while exergy analysis presents quantitative as well as qualitative results …

Thermal Analysis of CaZrO3 Coated Diesel Engine Liner Using 3-D Finite Element Method
Abstract: Abstract Results, obtained from many research papers it has been observed that in internal combustion engine about one third of total fuel energy is converted into useful work, about one third of the total fuel energy goes with exhaust gases and about one third of total fuel energy transfer to the coolant in form of heat through the cylinder wall, piston, valve etc. According to second law of thermodynamics, exhaust …

Thermal Analysis (Energy and Exergy) of Crystalline Silicon Solar Photovoltaic Module for Hazy Day
Abstract: Abstract With the growing population, demand for a renewable energy source has reached to peak level. It is necessary to have that source available easily and in sufficient quantity so that with the diminishing non-renewable source, basic need of energy can be fulfilled. This source can be the all-time available source, ‘solar energy’. Concern of most of the countries is just to make the availability of this source better and …

Max Planck: His Story of Winning the Nobel Prize in Physics
Abstract: The Nobel Prize is the most coveted and one of the best-known academic honors in the world. During 19th century, Germany, France, and UK were leaders in science and most of the Nobel Prizes were shared amongst their scientists. Max Planck is acknowledged as the Father of Quantum Physics. He got 74 nominations, including one from Albert Einstein, for Nobel Prize between 1907 and 1918 before he was awarded the …

Heat Transfer and Exergy Analysis of Methane-Air Flame Impinging on Plane Surfaces
Abstract: Exergy and heat flow have been numerically investigated for flame impinging on flat circular plates. The maximum work available when the system is brought to thermodynamic equilibrium state with its surrounding is known as the exergy of a system. This state of equilibrium of the system depends on the pressure, temperature, and composition of environment. Efficiency based on exergy is otherwise known as the second-law efficiency which measures the usefulness …
