Abstract:
A nickel alloy Inconel-718   is widely used in various fields such as automotive, aerospace etc.as it is having a highly specific strength material, excellent mechanical characteristics such high hardness, corrosion resistance, specific strength and bio-compatibility, due to this Inconel-718  is very much difficult to machine because its internal mechanical properties like ability of high strength at elevated temperatures, low thermal conductivity high hardness. In this experiment study base work will be based on comparative study of optimization of process parameter of turning operation of machining process like speed, feed depth of cut, surface roughness value to improve the cutting tool life with good quality of machining process, optimization of surface roughness and improvement in green manufacturing factors on INCONEL-718 by using PVD and CVD coated carbide inserts

Research Work:  In Air Conditioning System and its Impacts
Topic:Experimental Study of Impact of Air Distribution Techniques
Abstract:The present study introduces air distribution systems for improving indoor air quality and reducing the energy consumption of air-conditioning system.
Nowadays energy efficiency and indoor thermal comfort have become two main issues in heating, ventilation and air conditioning (HVAC) systems. However the balance between these two issues is difficult as the improvement of one is generally accompanied with trade-off the other. Hence, to achieve energy efficiency and thermal comfort simultaneously is of great significance to actual applications. This study firstly reviews the design parameters of HVAC systems of sterile spaces in hospitals and examined the influence of several key design parameters on air   distribution effectiveness by using analysis program. The parameters studied were space type, diffuser number, supply air temperature, cooling load, return location, total airflow rate, and secondary heating system. Six indoor spaces were
Investigated to develop a database: classrooms, office spaces, workshops, restaurants, retail spaces, and auditoriums. The recent research is reviewed on air-conditioning systems and indoor air quality control for human health. The influence of supplied momentum flow versus buoyancy forces is discussed, and geometries for high ventilation effectiveness are indicated as well as geometries for fully mixed flow. This study also investigated different combinations of floor/ceiling heating with mixing/displacement ventilation and their impacts on the indoor air distribution and ventilation effectiveness.

Topic: “EXPERIMENTAL INVESTIGATIONS INTO MACHINING OF α-β TITANIUM-ALLOY (Ti–6Al-4V) USING PVD & CVD COATED CARBIDE INSERT FOR GREEN MACHINING”
Abstract:
Titanium alloy Ti-6Al-4V  is widely used in various fields such as automotive, aerospace and bio-industry, nuclear plant and medical application because of titanium alloy is having a highly specific strength material, excellent mechanical characteristics such high hardness, corrosion resistance, specific strength and bio-compatibility, due to this titanium alloy is very much difficult to machine because its internal mechanical properties like ability of high strength at elevated temperatures, low thermal conductivity high hardness. Moreover, titanium alloys lower thermal conductivity and high specific heat limit the effective removal of heat developed during machining through workpiece and chips. In this experiment study base work will be based on comparative study of optimization of process parameter of turning operation of machining process like speed, feed depth of cut, surface roughness value to improve the cutting tool life with good quality of machining process, optimization of surface roughness and improvement in green manufacturing factors on titanium alloying α-βTITANIUM-ALLOY (Ti-6Al-4V) material by using PVD and CVD coated carbide inserts
