Structural Analysis, Material Optimization using FEA and Experimentation of Centrifugal Pump Impeller

In general the Efficiency of a centrifugal pump (ηo) = Mechanical efficiency (ηm) × Volumetric efficiency (ηv). Most of the study has been done in improvement of Hydraulic efficiency but overall efficiency depends on both factors Hydraulic and Mechanical. Mechanical components – for example impeller weight and structure produces a mechanical loss that reduces the power transferred from the motor shaft to the pump or fan impeller. Also strength of the pump reduces due to stress corrosion problems in impeller which can be minimized using alternate material having same/more strength. The modelling of the impeller will be done by using solid modelling software, CATIA. The meshing and boundary condition application will be carried using Hypermesh, it is also used to produce good and optimal meshing of the impeller to obtain accurate results and analysis has been done by using ANSYS. A static analysis on 3HP pump impeller has been carried out to examine the stresses and displacements of the centrifugal impeller. Conventional MS material is replaced with glass fiber composite material. After getting safe results from analysis, model will be fabricated and testing will be done on UTM.

Wavelet Analytical Study of Sulphur Dioxide as an Air Pollutant

Most of the sulphur dioxide in the atmosphere is anthropogenic by-product. It is one of the basic causes of acid rain worldwide. NAAQS set the level of sulphur dioxide in the atmosphere for the safety of human health and environment. Breathing of Sulphur dioxide becomes cause of many diseases concerned with respiratory system like Bronchitis, Asthma, etc. In the perspective of human health and environment protection continuous monitoring and analysis has become of great importance. Wavelet is a tool to analyze non-stationary signal and hence wavelet transforms provide excellent analysis of non-stationary time series of SO2 and extracts important information. Daubechies4 wavelet is orthogonal and compactly supportive and therefore, it is useful for multiresolution analysis of SO2 data. Wavelet transforms provide simple and accurate frame work for modelling the statistical behaviour of SO2 variation in the interest of public health and environment protection.

Convex optimization based Adaptive PID Controller in CSTR Plant with Deadline Constraint

Process control by error feedback is an effective method but it will not give proper feedback when plant show nonlinear data, so use optimization techniques which optimize in an effective manner but optimization algorithm takes more time converge so select effective algorithm, which shows effective time complexity for convergence. We propose Human dynamic optimization which shows significance difference.

Review on PID Controller with Intelligent System

This paper exhibited a survey investigation of tuning of Proportional Integral Derivative (PID) Controller for speed control of CSTR PLANT utilizing delicate processing strategies. CSTR PLANT engine is generally utilized as a part of businesses regardless of the possibility that its support cost is higher than the enlistment engine. Speed control of CSTR PLANT is pulled in extensive research and a few techniques are advanced. The PID controller is the generally utilized remunerating controller which is utilized as a part of nonlinear frameworks. This controller is broadly utilized as a part of a wide range of zones like aerospace, process control, manufacturing, automation and so forth. The tuning of PID parameter is extremely troublesome. There are different delicate processing systems which are utilized for tuning of PID controller to control the speed control of CSTR PLANT. Tuning of PID parameters is essential on the grounds that these parameters greatly affect the dependability and execution of the control framework

Recovery of RF Signal from Modulated Optical Signal

In previous proposed system, Radio frequency signal was transmitted through RF system. But the system had some disadvantages like non coherence and system was not efficient. This was overcome by using RF to optical domain converter. But that signal has to be recovered by converting the optical signal back to RF signal. This can be done by this system i.e. Optical to RF converter which is having photo detector, TIA and LNA. Here the modulated optical signal is detected by using photo detector, which detect the light signal and convert it to current signal. This current signal is converted to voltage signal and then required amplification is provided by using a LNA. Hence this system is a compact, and efficient system which is to provide a high speed optical to RF conversion.

Conversion of RF Signal to Optical Signal Using MZM

In previous proposed system, Radio frequency signal was transmitted through RF system. But the system had some disadvantages like non coherence and system was not efficient. Hence to overcome these drawbacks, RF over Fiber system is proposed. In the proposed system, RF signal is the message signal which is used to modulate the optical signal that has to be transmitted over the optical cable. Mach–Zhender Modulators (MZMs) are used to convert the RF signal to optical signal when the light cannot directly modulate for higher speed, the Lithium Niobate, Mach-Zhender Modulator (LN-MZM) is used, Continuous Wave Laser diode is used as the source and PIN diode is used as optical detector. To transmit the optical signal Polarization-Maintaining optical fiber (PMF or PM fiber) is used, this transmitted signal is detected at receiver by optical detector .Hence in RF over fiber system are small in size, these are flexible and is a very low loss technology using intensity modulation to transmit RF signal.
