Mechanical Engineers Say Proper Ventilation is Crucial for Your Small Business

2018-10-26T09:39:38+00:00

Engineers Explain How Good Ventilation Helps Your Business We’ll start with a fact that often startles people: (indoor air quality is a major health threat in the country).  According to the U.S. Environmental Protection Agency, the air quality inside buildings is often 3 to 4 times worse than the air outside. This goes against what most people think air pollution is like— fumes from cars and smoke stacks casting dark clouds over cities.  Heavy wall insulation, tightly fitted, non-opening windows ( Window Efficiency ), and commercial synthetic carpeting in modern buildings allows for the rapid build-up of contaminants inside without the chance to escape. Proper ventilation in your business that was designed by a licensed mechanical engineer(Licensed Mechanical Engineer ), is a key [...]

Material Engineers : A Pipedream?  Solar-powered cars have been thought of by many as an impossible pipedream. But the innovators behind, a fully solar-powered vehicle to be released in 2019.  GOING FULLY SOLAR A Car whose ability to use solar power has been thought of as an impossible feat.  Designed by the Dutch startup Lightyear, the “car that charges itself” can supposedly drive for months without charging and has a 400 – 800 km range. But is a solar-powered car feasible?Up until now fully solar-powered cars were not considered a realistic prospect, Solar Assisted Electric Vehicles (SAEVs) were considered the best possible option for solar cars, adding up to hundreds of miles to a cars range. But the Dutch Lightyear promises [...]

Electric Vehicle Batteries: Recycled

2018-07-18T14:04:45+00:00

  Material Scientist Ponder What to Do With Used EV Batteries  As electric vehicles become mainstream, mechanical engineers and chemical engineers are trying to address the big environmental question: what do we do with the used lithium-ion batteries? The batteries used in electric cars are physically large, last 8 to 10 years, and will account for 90 per cent of the lithium-ion battery market by 2025.  This will increase lithium demand fourfold, and more than double the demand for cobalt — two of their essential elements.  The price of cobalt has already risen by more than 80 per cent in 2018.   Most expert Material Scientists agree that a replacement hybrid car battery can range from $1,000 to more than $6,000.  The [...]

Semiconductor Record Fab Spending 2018

2018-05-14T10:33:13+00:00

Good News for Materials Scientists - Semiconductor Record Spending Fab spending reports show unprecedented high semiconductor equipment sales are being driven by a handful of well-known companies, and also by several new Chinese companies entering the semiconductor marketplace. An increase in overall fab spending (greenfield construction and equipment together) of 54 percent year-over-year (YoY) in China is expected.  Total spending in China rose from $3.5 billion in 2016, to $5.4 billion in 2017, and then is anticipated to be $8.6 billion in 2018, another 60 percent year-over-year (YoY). The demand for Materials Scientists to develop manufacturing processes and engineers to install and maintain the equipment will be huge as well . Fab Spending is Beyond Silicon Valley China-based companies [...]

Liquid crystal display (LCD) screens are omnipresent in our technologically saturated lives.  Having largely displaced the older CRT screens, LCDs make up a large portion of the digital imaging we see all around us.  They are present in everything from our ubiquitous smartphones and computer screens to digital billboards, wristwatches and vehicle and aircraft instrumentation.  How do flat panel LCD screens work? One can often find videos and articles documenting eager teardowns of new devices, but few delve beyond the hardware and into the materials and design behind the screen itself.  For this series of blog posts, we will be review some aspects of display technology , why they work, and how they are assembled.  To illustrate my points, I’ve disassembled a legacy Sony Ericsson® S500i phone [...]

Wind Load CFD Modeling for Rooftop Elements Compared to ASCE 7

2018-02-20T11:28:46+00:00

  Wind Load Comparison between CFD and ASCE 7 for Rooftop shapes Welcome back to our blog series on the phenomenon called Wind Load CFD Modeling and how it affects civil and mechanical engineers.  Wind Load is the force that blowing wind exerts on any device or structure that extends above ground level.  After an initial introduction to the factors that affect wind load on an object, I compared three different sets of wind load calculation methods using three simple objects, hypothetically placed on a 100-foot-tall building.  Starting with generic drag equation for the first equation, added two modification coefficients called "gust factor" and "exposure coefficient" for the second equation.    I used the model for rooftop objects for the [...]

Comparing Wind Load Calculation Methods

2018-02-21T15:26:59+00:00

Wind Load Calculation Wind Load Calculation is an overview of the force that blowing wind exerts on a tall object.  A number of factors that influence the actual wind load on a real building, include the surrounding terrain, nearby structures,  trees, and typical weather patterns for the area.  Comparing wind load calculations are most complicated . Calculations try to account for as many of these external factors as possible, to the point where the wind load section in American Society for Civil Engineer’s ASCE 7 standard, spans five chapters and over 100 pages. Fig 1: Wind load calculation example structures ASCE 7's Applications Comparing one of ASCE 7’s Applications with the two equations [...]
