As we know that fins are basically extended surface, which is used to increase the heat transfer rate, this is basically a secondary surface mounted on primary surface to augment heat transfer from it. This study presents the result of computational numerical analysis of air flow and heat transfer. Pin fin become helpful to enhance heat transfer with in a suitable performance. By above chosen analyzed material AlHE30, the scope of present work is comparing numerical analysis and performance evolution of rectangular (ALHE30) fins under natural and forced convection conditions.

The objective of this paper is to investigate the effect of adding different percentage of sodium hydroxide on the engineering properties of nearby clayey soil. In the present study, the amount of sodium hydroxide is taken as 2%, 4%, 6%, 8%, 10%, by weight of the soil as soil stabilizer for the investigation purposes. From the present study it is found that 6% of sodium hydroxide is best or we can say that it is optimum for reducing the optimum moisture content of the soil as the value of OMC reduces from 15.4% to 9.87%. After further addition of sodium hydroxide the OMC starts increasing which is not good for the clayey soil. Also from the investigation it is found that the maximum dry density (MDD) of the natural soil increases upto 5% to 6% of sodium hydroxide and after that MDD starts decreasing. The value of maximum dry density (MDD) increases from 1.72g/cc to 1.91g/cc. After addition of sodium hydroxide, the value of UCS increases from 3.47kg/cm2 to 4.12 kg/cm2 upto 6% addition of sodium hydroxide.

In day to day life we come across many process, in present concept we were used ALHE30 material as fin for cooking utensils. Fuel consumption is the very important role in India. The present work relates to improve the heat transfer effectiveness of cooking utensils which are commonly used as kitchen gas ranges by the applications of fins and its performance with unfinned vessel. Preliminary work performed on the finned vessel showed that 25% to 35% and cooking time is saved correspondence 15% to 25% saving in the fuel consumption. To dissipate heat at faster rate, different heat transfer enhancement methods have been suggested in literature so, the concept of finned cooking vessel is a new initiative even though fins are widely used in industrial applications line heat exchangers, boilers, radiators, refrigeration’s and air conditions. In our project work, an effort is made to apply the engineering concept to the day-to-day application by using fins or extended surfaces in the cooking vessel. Cooking vessel is a very important heating process which required large amount of fuel. Hence for, this work lies in saving fuel by reducing heat loss during cooking process.
