Ballast Fouling in Railways
In this transportation/railway engineering blog post we discuss ballast fouling, a rail performance issue that each year costs millions of dollars for repair and maintenance in tracks all over the world.
Drawdown in Aquifers: Theis and Hantush-Jacob Well Functions
In this hydraulics/hydrology/hydrogeology blog post, we discuss two simple models used to assess aquifer drawdown due to groundwater flow in confined and semiconfined wells.
Biomass Gasification
In this chemical engineering/energy engineering blog post, we discuss biomass gasification, an energy conversion technique that can be used to produce hydrogen gas and other valuable chemicals.
Vertical-Axis Wind Turbines
In this energy studies/aerodynamics/aerospace blog post, we discuss vertical-axis wind turbines (VAWTs), an underrated renewable energy solution that has recently drawn the interest of the research community.
Fresnel Diffraction and the Cornu Spiral
In this optics blog post, we explore Huygens-Fresnel diffraction and related concepts, such as Fresnel zones, Fresnel integrals, and the Cornu spiral.
Freezing Time of Foods: Plank’s Equation and Pham’s Simplified Model
In this blog post, we discuss two simple heat transfer-based models for determination of the freezing time of foods. Two solved example problems are included.
Elliptic Circulation Distribution and Downwash
In this aerospace engineering blog post, we discuss elliptic circulation distributions and induced velocity (downwash). Two solved examples are included.
The Bruun Rule and Sea-Level Rise
In this water resources engineering/geomorphology blog post, we study the Bruun rule, a simple relationship between shoreline regression and sea-level rise that has been a mainstay in coastal science for over half a century.
Electrokinetics and Electroosmotic Flow
In this fluid mechanics/transport phenomena/surface chemistry blog post, we discuss basic aspects of electroosmotic flow. Topics covered include electric double layer, Poisson-Boltzmann equation, and non-Newtonian EO flow.
