Engineering Solutions for Everyday Problems

As environmentally-conscious engineers, we here at Glew Engineering do what we can to save energy and resources both around home and around the office.  This might mean choosing products that are more environmentally friendly or energy-efficient.  It might mean using our surroundings to our advantage, like pulling cold air through a home or office [...]

Wind Load CFD Modeling

Figure 1: Wind load calculation example structures Welcome back to our blog series on the phenomenon called wind load 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 [...]

Comparing Wind Load Calculation Methods

Our last blog entry was an overview of how to calculate wind load, the force that blowing wind exerts on a tall object.  There are a number of factors that influence the actual wind load on a real building, including the surrounding terrain, nearby structures and trees, and typical weather patterns for the area.  The [...]

Wind Load Calculations and Modeling

 Part 1 of our Wind Load Series “Wind load” is a calculated value representing the total force on a structure or object cause by pressure from wind moving over it.  In this blog series, we will discuss different methods for wind load calculations, the factors that influence its magnitude, and the effects a high wind load [...]

Flat Panel and LCD Screens, Part 1

Figure 1: Powered LCD screen of a Sony Ericsson S500i at 200x magnification. 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 [...]

Window Energy Efficiency: Solar Heat Gain and Visible Transmittance

Figure 1: Sunlight on high-rise windows In my last blog post, I wrote about the conduction and radiation of thermal energy through windows and the thermal transmittance value, called the U-Factor, that characterizes that heat transfer.  The U-factor is useful in evaluating window performance and making wise decisions when specifying components for a building, but [...]

Window Energy Efficiency: Thermal Transmittance

Figure 1: Windows catching sunlight By Magda S [ Content License] In our last blog post, I wrote about the thermal resistance (R-value) and transmittance (U-factor) of insulation and windows.  The R-value represents how well a material prevents heat transfer through its thickness, and U-factor is its inverse, representing how much heat a material will conduct [...]

Energy Efficiency in Building Materials, Insulation and Windows

Figure 1: FLIR image of two houses showing energy loss. Colors towards red on the scale indicate warmer surfaces and more energy loss. The basic principle behind thermal insulation is simple to understand.  The harder it is for heat to travel through a material, the better insulator that material will make.  In this blog, I’m [...]

Italian Masters: Leonardo da Vinci – Artist, Engineer, Scientist

Figure 1: Leonardo da Vinci, by Francesco Melzi Over the course of this blog series, I have written about a number of Italian Masters of science and engineering, from astronomers like Galileo and Cassini to physicists like Torricelli and Venturi.  I’ve saved the best for last, however: Leonardo da Vinci.  He is the quintessential renaissance man who fits [...]

Thermal Expansion in a Glass and Aluminum Window: Part 2

Figure 1: Simplified model of an aluminum-glass window In last week’s last blog, we explored the causes and effects of thermal expansion in solid materials.  The expansion and contraction of a material based with temperature must be considered in mechanical engineering design projects, since it can impose high and potentially-damaging internal stresses.  We used a simplified aluminum-framed window to demonstrate [...]
