Design and analysis of a car radiator fan assembly to mitigate the effect of aeroacoustic dipole noise

Engine cooling fans contribute a major portion of the total noise generated by the different mechanisms in a car. Therefore the design aspect of the fan blades and housing need impeccable research and careful machining to limit the noise level to a bare minimum. The noise generated from the design aspect of the fan can be grouped into two categories, rotational and irrotational. The rotational domain takes into consideration the effect of turbulence and inflow distortion while the irrotational domain considers the effects of laminar boundary layer vortex shedding, blade interaction with tip clearance and the phenomena of blade stall. The objective is to analyze the acoustic behavior and response from the fan blade and housing when exposed to incoming airflow in a car. The process due to which the aeroacoustic dipole noise is generated is investigated and the parameters affecting the noise level are assessed. The flow and acoustic analysis are carried out on SOLID WORKS flow simulation and the generated data for our particular case is represented on a graphical scale against frequency. The causes behind noise generation in a fan assembly is studied and major emphasis is laid on the aerodynamic factors, which affect the noise generation in the radiator cooling fans. After validating the theoretical procedure, an attempt is made to redesign the existing fan assembly structure by adding grills and MPP dampeners and source modification is done to reduce noise levels.

A review on object detection from Unmanned Aerial Vehicle using CNN

UAV stands for unmanned Aerial Vehicle, which can be as small as birds, regular drones or as big as private aircraft with no pilot on board. Since there is no one onboard UAV is remotely controlled. UAV is currently being used for a different purpose, examples are spy footages, sky view footage, reconnaissance, attacking roles, aerial surveillance, motion picture filmmaking, disaster rescue, parcel delivery, warehouse management, and other uses. Due to UAV multi-functionality and portability especially drones demand is growing faster, therefore, people need systems that work with the UAV (drones) to detect objects in real-time for military, safety reconnaissance, and surveillance. This paper review approaches to detect objects from camera view and from UAV scenes using machine learning algorithms. The growth of computer vision systems initiated better algorithms using huge training and testing datasets, faster GPU and CPU so that systems can achieve state of the art object detection system by training and classifying the data using machine learning approach. Since there are different orientation, background, occlusion in an image, object detection is not an easy task. The goal of object detection is to categorize images and video feeds from UAV into common categories.

Comparative study of time history analysis of cold formed steel frame

Cold-Formed Steel (CFS) framing has been successfully used in a variety of construction applications for many years. Common uses include nonstructural partitions and ceilings, exterior curtain wall and façade support, and complete load-bearing structures, including lateral force-resisting systems (LFRS). Recent advances in the understanding of CFS framing and ongoing research related to the Analysis of seismic force-resisting systems (SFRS) are expected to expand the use of cold-formed steel framing into more complex, robust structural systems. This project focuses specifically on the use of cold-formed steel SFRS in buildings. Standard analysis procedures apply to cold-formed steel analysis. However, because CFS shapes often include elements with high width-to-thickness ratios, limit states not common to other construction materials must be considered in the design process. These limit states are discussed in the Project. The analysis is carried out using E-TABS software. To analyze and compare the structure the 2 models are formulated of 5 stories and 10 stories. The model is symmetric in plan having a 2×2 grid. The main objective of this study is to examine the behavior of cold-formed steel frame considering different modeling systems. All the above cases are analyzed for El Centro earthquake records i.e. Time History Analysis.

Thermal flexure analysis of orthotropic plate using trigonometric shear deformation theory

This paper presents the thermal flexure analysis of orthotropic plates subjected to sinusoidal thermal load linearly varying across the thickness. Analytical solutions for thermal displacements and stresses are investigated by using a trigonometric shear deformation plate theory which includes different functions in terms of thickness coordinate to represent the effect of shear deformation. The theory presented is variationally consistent, does not require shear correction factor, and gives rise to transverse shear stress variation such that the transverse shear stresses vary parabolically across the thickness satisfying shear stress-free surface conditions. Governing equations of equilibrium and associated boundary conditions of the theory are obtained using the principle of virtual work. The Navier solution for simply supported orthotropic plates has been developed. The validity of the present theory is verified by comparing the results with various Shear Deformation Theory.

Medical wastage plastic use in concrete

Concrete is being most widely used as a construction material in the world. In recent times, there is a lot of development in the field of concrete technology due to its high strength. An experimental investigation was carried out to study the mechanical prosperities of medical wastage plastic concrete such as compressive strength, split tensile strength and flexural strength. The experimental work was taken up on M20 grade of concrete as per IS 10262:2009 having mix proportion 1:1.5:3. Cubes of size 150 mm x 150 mm x 150 mm for compressive strength were casted; cylinders of size 300 mm length and 150 mm diameter for split tensile strength were casted and beams of size 100 mm x 100 mm x 500 mm for flexural strength were casted. Various specimens were tested after 7 and 28 days of curing. The experimental work represents the details of the experimental investigations and graphical format to determine conclusion.

Study on partial replacement of cement by sugarcane bagasse ash and wood ash

In creating nations, where rich agrarian and modern squanders, are released, these squander can be utilized as potential material or substitution material in the development business. This will have a great preferred position of decrease in the expense of development material. Notwithstanding its negative ecological effect bond is additionally one of the most costly materials when contrasted with different constituents of concrete. The crude materials for the bond generation like lime are additionally being misused in enormous amounts which may bring about coming up short on them, as it is anticipated to occur in certain spots of the world. The second biggest nation of sugar creation after Brazil in India. Because of which, there is an expansion in the measure of bagasse as a result of the sugar factory. Sugar stick bagasse cinder is the waste result of the ignition of bagasse for vitality in sugar ventures because of which it is effectively accessible and shoddy. Sugar stick bagasse fiery remains (SBA) is discarded in landfills and is presently turning into an ecological issue. The Wood fiery remains used was gotten from tree wood. In the wake of social event, the wood fiery remains was clearly warmed
