Case Study

Pedestrian walkability index

The objective of this paper is to study the walkability index and to rate the areas based on safety, security, and convenience to the Pedestrian environment. This study evaluates and reports the existing condition of Pedestrian facilities in the area considered and its analysis from both qualitative and quantitative point of view, comparing it with a study of various standards stipulated by HCM and IRC parameters which could be used for the design of Pedestrian facilities. The survey and analysis is done in city Davangere, Karnataka. To get the overall measure of Pedestrian Walkability Index of the city, it is classified into two different areas i.e. Commercial and Shopping areas, are selected for the study. The Pedestrian Walkability Index (PWI) survey consists of 2 components i.e. Field walkability survey and a Pedestrian interview survey. The Pedestrian LOS and adequacy of footpaths was carried out based on the guidelines of HCM 2000 and IRC:103-1988 respectively. In the selected areas, the length of the stretch and width of the available footpath was measured. The Pedestrian volume counts were taken during peak hours and the average pedestrian walking speed was computed manually. From these data, the Pedestrian flow, density is calculated and the LOS is obtained. And based on the Pedestrian volume in the areas, the adequacy was checked and the recommended footpaths widths were proposed as per the recommendations of IRC. In the widths of the selected areas in Davangere city, only 16.7% are inadequate and the remaining 83.3% is adequate.

CFD based heat transfer analysis in circular tube with different orientation of insert for laminar flow

The process industry is continuously working to incorporate enhancement in heat transfer. Enhancement techniques can be classified as active methods, which require external power or Passive methods, which require no direct application of external power. The enhanced surfaces are routinely used to improve the thermal and hydraulic performance of heat exchangers. This thesis presents a CFD analysis of heat transfer problem. The enhancement of heat transfer with mass in a tube has been investigated without and with insert. The combinations of without inserts, two inserts, four inserts, six inserts, eight inserts, and ten inserts have been used. An 800 mm long pipe with 26 mm inner diameter and 30 mm outer diameter is considered for our simulation. It was noticed that outlet temperature decreases with increase in Reynolds number when insert orientation was changed.

Smart garbage bin

Garbage monitoring has become an essential issue for most of the cities in the world. The detection, monitoring, and management of wastes are one of the primary problems of the present era. Due to the negligence of authorities and carelessness of public, long-term problems such as bad odor and harmful diseases occur. The traditional system of waste collection and management is effective only in those areas where garbage bins become full on a daily basis. But in certain areas, garbage production is low whereas the garbage collection trucks check the garbage level each day. This checking and collection process leads to heavy fuel loss. In remote locations, garbage trucks do not arrive to pick the garbage on time leading to garbage overflow. To overcome these problems we have introduced “Smart Garbage Bin” as an effective system. The smart garbage bin employs a level detector that detects the amount of garbage in the bin. When the level of garbage in the bin reaches 75%, a notification is sent to the operator of the garbage collecting vehicle through a web interface.

Enhancing the thermal conductivity of polymer composites

Carbon fiber-reinforced Polymericomposites (CFRP) are becoming most important structural materials for aircraft structures, satellites, missiles, and other aerospace applications. However, extending these materials for thermal and electronic applications is restricted by the poor thermal conductivity. In order to improve the thermal conductivity of CFRP composites, two methods were followed. In the first method, the polymer matrix was made conductive by incorporating various fillers (copper powder, carbon nanotubes and graphene ). Using these conductive matrices, CFRP composites were developed by vacuum bag molding technique. In the second approach, in addition to fillers, a continuous copper mesh was embedded for fabricating the CFRP composite. The in-plane and out- of -plane thermal conductivity of the CFRP composites was measured by hot disc. From the results obtained, it was found that the in-plane thermal conductivity of the CFRP decreased with the filler inclusion whereas the out- of- plane conductivity of the composite was enhanced. In case of copper mesh embedded CFRP composites, both in the plane and out of plane thermal conductivity was enhanced Further, the effect of filler addition and copper mesh inclusion on the mechanical strength was studied by measuring the interlaminar shear strength(ILSS) and was substantiated by NDT characterization.

Implementation of Substation Automation Systems using IEC 61850

Electric power system substations are being modernized to better serve user requirements for more efficient communication and more comprehensive protection and to facilitate future expansion by installing and applying higher-performance IEDs. There is a demand for a Substation Automation System (SAS) that is simple to integrate and provides high performance and flexibility. IEC 61850 capacities provide interoperability and advanced communications capabilities in substation protection, coordination, control, monitoring, metering, and testing. IEC 61850 is the result of the efforts of IEC Technical Committee 57 (TC57) to produce an open standard for substation modelling and communications. Substation configuration description language (SCL) is used in IEC61850-based substations to create substation configuration description files that contain full information about the substation. The main purpose of this format is to ensure that IED capability and substation descriptions are exchanged in a compatible way between the IEDs.

Studies of effect of hardness property of aluminium metal matrix composites by heat treatment

The Al6061 alloy matrix materials exhibiting excellent mechanical properties with the addition of SiC and B4C particulates as reinforcement. Liquid Metallurgy route is preferred for preparing composite specimen materials. Composites were subjected to heat treatment process followed by quenching in castor oil. Then all the specimens are subjected to artificial aging at a temperature of 120˚C for different time duration. Using Rockwell hardness testing machine, hardness properties are examined for the composite materials before and after heat treatment. It is observed that Al6061 metal matrix composite experimented under identical heat treatment conditions shows a considerable increase in hardness.
