Integrated Review of Thermo-Physical Properties of Different Ceramic Coatings to Make them Suitable for Internal Combustion Engines
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 13 Issue: 10 Thermal barrier coating using many ceramic powders is being done in internal combustion engines for more than two decades now. Thermal spray techniques are extensively used for coating of these powders over piston top, cylinder walls and valves of the engine. These coatings have to bear thermal stresses during combustion in the engine thus wear and tear of ceramic coating occurs. The pre...

Conjugate Cooling of a Protruding Heater in a Channel with Distinct Flow Constraints
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 13 Issue: 11 The conjugate cooling of a single block heater mounted on a conductive wall of a parallel plates channel was investigated under distinct laminar airflow constraints: fixed flow rate, fixed channel flow pressure drop and fixed pumping power. The heater was cooled by direct forced convection to the airflow and by conduction through its contact with the channel wall. The investigation was p...

Failure Analysis of a Universal Coupling using Finite Element Method
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 13 Issue: 9 Generation of stress, displacement and strain in a universal coupling has been analyzed. Circumferential stress is applied at the yoke slot and also on the hub and simulated separately. The simulation is carried out with the help of SolidWorks 2010. To show the effect of temperature rise due to friction at the yoke slot, thermal load is gradually increased at the slot. The results are de...
