Title : Cooling Tower Performance and Determining Energy Saving Opportunities through Economizer Operation: A Review
Country : India
Authors : Dhruvit Joshi || Chetan Jaiswal

Abstract: Cooling towers form an important part of chilled water systems and perform the function of rejecting the heat to the atmosphere. Chilled water systems are observed to constitute a major portion of energy consumption in air conditioning systems of commercial buildings and of process cooling in manufacturing plants. It is frequently observed that these systems are not operated optimally, and cooling towers being an integral part of this system present a significant area to study and determine possible energy saving measures. More specifically, operation of cooling towers in economizer mode in winter (in areas where winter temperatures drop to 40°F and below) and variable frequency drives (VFDs) on cooling tower fans are measures that can provide considerable savings.

Title : Multiple Objective Optimizations of Parameters in Rotary Edm of P20 Steel
Country : India
Authors : Jayesh G || Dr. Santhosh Kumar N

Abstract: Electrical discharge machining (EDM) is one of the advanced methods of machining. Most publications on the EDM process are directed towards non-rotational tools. But rotation of the tool provides a good flushing effect in the machining zone. Optimization of process parameters in rotary EDM to arrive at the best manufacturing conditions, is an essential need for industries towards manufacturing of quality products at lower cost. This paper aims to investigate the optimal set of process parameters such as work piece polarity, current, pulse ON and OFF time and tool rotational speed in rotary EDM process to identify the variations in three performance characteristics such as material removal rate, tool wear rate and surface roughness value during machining of P20 die steel using copper electrode. Based on the experiments conducted using L18 orthogonal array, analysis has been carried out with Grey relational analysis. Response tables and graphs were used to find the optimal levels of parameters in rotary EDM process. Confirmation experiments were carried out to validate the optimal results.

Title : Influence of Chloride Compounds on the Swelling and Strength
Properties of Expansive Subgrade Soil
Country : India
Authors : G.Radhakrishnan || Dr M. Anjan Kumar || Dr GVRP Raju

Abstract: The engineering properties of expansive soil containing montmorillonite clay mineral are highly sensitive to moisture variations. The cyclic wetting and drying process in the expansive subgrade soil leads to the failure of pavements constructed on them. In order to improve the properties of subgrade soils and the pavement system performance, stabilization of subgrade soil is only the alternative. In the process of stabilization, usage of chemicals has gained prominence due to their easy applicability and adaptability. In
general, lime is a conventionally used chemical for the last two decades and investigations reveals that chloride compounds could also be used instead of lime, because of their active contribution towards the cation exchange with soil and also their solubility in water causes easy application to soil grains. In the present study the performance of different chloride compound chemicals like Ammonium chloride (NH4Cl), Magnesium Chloride (MgCl2) and Aluminum Chloride (AlCl3) on the swelling and strength properties expansive soil were studied. Evaluation is based on the laboratory test results on the soil collected from coastal area of Andhra Pradesh, India..

Title : Effect of Soil-Structure Interaction on High Rise RC Building
Country : India
Authors : Mr. Rahul Sawant || Dr. M. N. Bajad

Abstract:Most of the civil engineering structures involve some type of structural element with direct contact with ground. When the external forces, such as earthquakes, act on these systems, neither the structural displacements nor the ground displacements, are independent of each other. The process in which the response of the soil influences the motion of the structure and the motion of the structure influences the response of the soil is termed as soil-structure interaction (SSI). In this paper, the interaction between the super-structure and sub-structure is investigated by modelling the soil as simple as possible to capture the overall response of the system. As new analytical hysteresis rules and more advanced tools of analysis have been developed in recent years, first the nonlinear response of a single-degree-of freedom system which can be representative of a broad range of newly designed structures, is investigated while allowing for flexibility of the soil-foundation system and SSI effects. This non-linear frame model is high rise residential building of G+42 storeys located at MUMBAI and time history of ELCENTRO is used to study the response of the model in ETABS.

Country : Bangladesh
Authors : Md. Abul Kalam Azad || R.K. Mondal || Sajal Kumar Dhali || Shamima Sultana1

Abstract:The unsteady free convection and mass transfer flow past an exponentially accelerated infinite vertical plate with variable viscosity and thermal conductivity has been investigated in this work. The plate temperature is raised linearly with time and the concentration level near the plate is raised to C  .The governing boundary layer equations of momentum, temperature and concentration are the second order couple linear partial differential equation. Mathematical formulation of boundary layer equations have been nondimensionalized by using dimensionless variables. These non-dimensional boundary layer equations are nonlinear and partial differential equations and are solved by finite difference method. For the different physical parameters the results of velocity, temperature and concentrations are displayed in the form of level curves. Skin friction and Nusselt number are also described in graphically.

Title : Thermodynamic analysis of LiBr and water based vapour absorption air-conditioning system utilizing waste exhaust heat energy of Diesel Engine
Country : India
Authors : Shakti Prakash Jena || Smrutirekha Mishra

Abstract:The potential of an engine exhaust driven LiBr-water based absorption system for air-conditioning is analyzed in this paper. The effects of generator, condenser, evaporator, and absorber temperatures on the energy and exergy performance of the absorption system were observed. The results indicate that the coefficient of performance increases with increase in evaporator temperature, but decreases with increase in condenser and absorber temperature. The exergy analysis of the system indicates that air cooled condenser and absorber shows higher exergy losses than the generator and evaporator. A small scale LiBr-water based absorption system can be feasible to operate using exhaust heat energy from a diesel engine.
