Performance Calculations and Optimization of a Fresnel Direct Steam Generation CSP Plant with Heat Storage (Mechanical Project)
This study deals with the performance calculations of a 9MW linear Fresnel CSP plant with direct steam generation built by the Solar Division of the CNIM Company. The aim was to calculate the Continue reading
Thermoeconomic Analysis and Optimisation of Air-Based Bottoming Cycles for Water-Free Hybrid Solar Gas-Turbine Power Plants (Mechanical Project)
The growing worldwide energy demand and the impacts of climate change due to anthropogenic greenhouse gases emissions are among the major issues facing humanity. The global energy system, responsible for most of the greenhouse gases emissions, is therefore at the heart of Continue reading
Analysis of a new district heating line: Evaluation of heat losses and hydraulic facilities (Mechanical Project)
The aim of the project is to analyze the enlargement of the district heating line located in Gävle, evaluating the hydraulic facilities and calculating the heat losses with different insulation thicknesses to choose the best insulation thickness for the pipes. To choose the Continue reading
Elaboration of Thermo-Economic Models of Solar Gas-Turbine Power Plants (Mechanical Project)
For the short and mid-term outlooks a reduced grow rate in the worlds energy demand is unlikely. The increased demand for fossil resources will therefore be accompanied by Continue reading
Experimental Analysis Of Variable Capacity Heat Pump System Equipped With Vapour Injection And Permanent Magnet Motor (Mechanical Project)
This study analyzes the performance of variable capacity heat pump scroll compressor which is equipped with vapour injection and permanent magnet motor. Refrigerant used in the system is R410A. The study is divided in two phases. In first phase, tests are Continue reading
Thermal Simulation of Hybrid Drive System (Mechanical Project)
Safety, performance and driving comforts are given high importance while developing modern day cars. All-Wheel Drive vehicles are exactly designed to fulfill such requirements. In modern times, human concern towards depleting fossil fuels and cognizance of ecological issues have led to Continue reading
Modular Hybridization of Solar Thermal Power Plants for Developing Nations (Mechanical Project)
The current energy scenario in the developing nations with abundant sun resource (e.g. southern Mediterranean countries of Europe, Middle-East & North Africa) relies mainly on fossil fuels to supply the increasing energy demand. Although this long adopted pattern ensures Continue reading
Comparison of different Line Source Model approaches for analysis of Thermal Response Test in a U-pipe Borehole heat Exchanger (Mechanical Project)
Ground Source Heat Pumps (GHSPs) is a relevant application and around 3 million installations are setting up at the beginning of 2010 (IEA ECES Annex 21). The improvements in GSHPs are currently focused on the optimization of the system and the reduction of Continue reading
Development of an Experimental Permanent-Magnet Motor Drive (Electrical/Electronics Project)
The report describes the development and preliminary investigation of an experimental drive system, of which the central component is a permanent-magnet synchronous motor optimized for a hybrid electric vehicle. The maximum Continue reading
Transverse Thermoelectric Effects for Cooling and Heat Flux Sensing (Mechanical Project)
While thermoelectric technology has developed steadily over the last 50 years, transverse thermoelectrics have generally been ignored in the industrial and commercial uses of thermoelectric devices to date. Continue reading
Method Development for Investigation of Real Effects on flow around Vanes (Mechanical Project)
In the development of turbo machinery components it’s desirable to not spend more time than necessary when setting up Continue reading
Optimization as a Thermodynamic System (Mechanical Project)
As we know that nature made the things optimized in all point of views, also it is supposed that nature works under some evolutionary process. Since there was no such Evolutionary Structural Optimization (ESO) method having strong Continue reading
Design and Fabrication of Electrothermal Micromotors and Compliant Mechanisms for Spatial Parallel Micromanipulators (Mechanical Project)
In this project a new class of spatial micromechanisms employing compliant joints and electrothermal motors has been developed. The spatial micromechanisms contain three limbs driven by Continue reading
Hotspot Remediation using Germanium Self Cooling Technology (Mechanical Project)
Localized thermoelectric “self cooling” in semiconductor materials is among the most promising approaches for the remediation of on-chip hot spots resulting from the shrinking feature sizes and faster Continue reading
On-Chip Thermoelectric Cooling of Semiconductor Hot Spot (Mechanical Project)
The Moore’s Law progression in semiconductor technology, including shrinking feature size, increasing transistor density, and faster circuit speeds, is leading to increasing total power dissipations and heat fluxes on silicon chip. Moreover, in recent years, increasing Continue reading
Piezoelectrically Driven Thermoacoustic Refrigerator (Mechanical Project)
Thermoacoustic refrigeration is an emerging refrigeration technology which does not require any moving parts or harmful refrigerants in its operation. This technology uses acoustic waves to pump heat across a Continue reading
Competitive Thermokinetics and Non-linear Fire Behaviour (Mechanical Project)
The prediction of the behaviour and spread of fires in the bush has always been fraught with a large number of unknowns, not the least of which has been the seemingly capricious nature of fire itself. Operational bushfire prediction systems, developed Continue reading
A comparison of power harvesting techniques and related energy storage issues
Power harvesting, energy harvesting, power scavenging, and energy scavenging are four terms commonly used to describe the process of extracting useful electrical energy from other ambient energy sources using special materials called transducers that have the ability to convert one form of energy into anothe Continue reading
