The Design Sense

Mechanical Design and More   Why Design? The new era is flooded with products - Virtual or Physical. And with no surprise, everything needs to be designed. We are doing it from long back, since we are bringing something new or may be inventing. Design is the medium which brings your thoughts into a physical (nowadays virtual) form.   Virtual/Web design Remember the old days websites or software packages - They were largely comprised of text, and design layout did not

Effect of the type of mesh on a Pipe flow problem

The project explains how the type of mesh can influence the results obtained for the mixing of flow in a pipe. The simulation is done on a cloud-based CAE platform called SimScale. The link to the project is here. This project is a part of the SimScale Professional Training on CFD (Computational Fluid Dynamics).   The pipe flow geometry, originally uploaded by the SimScale Staff, available in the public projects.   For this internal flow problem,

Boilers: Introduction and Classification

The boiler system comprises a feed-water system, steam system, and fuel system. The feed-water system supplies treated water to the boiler and regulate it automatically to meet the steam demand. Various valves and controls are provided to access for maintenance and monitoring. The steam system heats and vaporizes the feed water and controls steam produced in the boiler. Steam is directed through a piping system to the application. Throughout the system, steam pressure is regulated using v

Strength calculation

hello All,  i am working as a design engineer and i am working on sheet metal structures. i am looking at the calculations to decide on the thickness of sheet metal to carry a particular load. i calculated the sectional modulus of the design based on the cross sectional area of sheet metal and it is well within the sectional modulus of material. I would like to know werher the approach is right or are there other calculations which i should do before deciding the thickness?. reque

Pre- Crash Sensors for Pre-Crash Safety

Many research and development have been conducted  to meet society needs for safer vehicles. Particularly, occupant protection system such as air bags, developed and introduced in order to reduce occupant injuries in crashes, are currently installed in most vehicles making significant contribution to safety.   Meanwhile, many studies have been made into the development of active safety technologies that help to avoid crash accidents. Unfortunately the current situation is that the acti

V2V (Vehicle to Vehicle) Communication

V2V (Vehicle to Vehicle) Communication

The objective of ambient intelligence is to create an intelligent daily space, which is immediately usable and integrated into our homes, our offices, our roads, our cars, and everywhere. This new concept must be invisible; it must blend in with our normal environment and must be present when we need it.   One of the application of this concept consists of providing our cars and roads with capabilities to make road more secure (information about the traffic, accidents, dangers, possibl

Automated Manual Transmission

MT (manual transmission) uses simple spur gears providing excellent transmission efficiency and thus typically get 10% or better fuel mileage than current ATs (automated transmissions). The object of the ATM (automated manual transmission ) is to automate starting and gear shifting while retaining this excellent fuel efficiency. A round of fierce competition was triggered among European manufacturers to see who would be the first to develop what is generally known as a conventional AMT that atte

DRIVERLESS CARS

For generations, the automobile industry has been a source of innovation and economic growth. The ability to drive is a symbol of mobility and independence that spans generations. Clearly, automobiles play a significant role in our lives and afford many benefits to society.   Yet for all benefits conferred on society, no other invention in the history of civilian technology has caused as much harm as the automobile. Every 30 seconds. someone dies in a traffic accident, adding up to wel

CNG in India

Compressed natural gas(CNG) is a fuel that needs no introduction.  it is a cheap fuel to make and use, which is why it is so widespread in public transport. Not to mention that the second hand car market is greatly supported by CNG kits. vehicles like the Honda Civic, Accord and Toyota Corolla are favorites to be bought second hand and then have green fuel kits used to make them easy on the pocket. With diesel deregulation soon to kick in, the price of the oil will head north soon, so CNG seems

Desicant Cooling System

In the last 10 years, evaporative and desiccant cooling technology for air conditioning has increased as an alternative for air conditioning systems has increased as an alternative to the conventional vapour compression systems. A typical system combines a dehumidification system that uses a rotary desiccant wheel, with direct or indirect evaporative systems, allowing a filtered and cooled air supplying temperature, humidity and speed conditions that propitiate environmental thermal comfort, eve

Experimental Analysis of an Air Washer

Hello World,   Today i will like tell you all about my 4th year project which was on the topic of experimental analysis of an air washer. In the recent sanario the peoples are slowly getting conscious about the beast(pollution) intended to destroy our beautiful sphere(earth). This pollution had drastically spread in our world drastically in few years. It is sad to say but we are only responsible for it. The careless burning of fossil fuels, heavy growth in industries and invention

Last Post -- Time to Hang It Up

Mechanics Corner     A Journal of Applied Mechanics and Mathematics by DrD     © Machinery Dynamics Research, 2017 Last Post Time to Hang It Up     This will be the final post of Mechanics Corner here on Mechanical Engineering Forums. It has run almost exactly two years, and there have been ups and downs along the way. In this final post, I want to reflect a bit on my original goals for the blog, and also on what has actually happened. When our host first proposed to me t

A Problem in Statics & Dynamics, #34

Mechanics Corner     A Journal of Applied Mechanics and Mathematics by DrD, # 34     © Machinery Dynamics Research, 2015 A Problem in Statics & Dynamics           Introduction         A problem was recently posted on this Forum, requesting help, that has led me to consider a somewhat more general problem for this post. The scope of this post will include the original problem, although not by the method required there, but will also go beyond to a more general geometry.

What are hydraulic cylinders,working principles !!

Hydraulic cylinders haven’t really changed a lot over the years. The manufacturing processes are much more streamlined and the tolerances are much tighter, but for the most part cylinders are still the hard working push/pull tools they have always been. These things have literally shaped the world around us. Anything that gets lifted, pushed, hauled, dumped, dug, crushed, drilled or graded has gotten that way by some truck, crane, dozer or tractor using a hydraulic cylinder. But how do hydraulic
