Pipe Stress Diagram

Pipe Stress: Simple, right? Just a hollow circle transfering stuff… If only it were that simple. Here at Stressman, we tackle pipe behavior challenges on a weekly basis. Pipes are almost like organisms. Restrain one part, and while you might be helping with load-controlled stresses, the strain-controlled ones could go through the roof. Finding that […]

Mathematical Notations

Mathematics is the universal language that bridges the gap between theoretical concepts and practical applications. As engineers, we rely on precise mathematical notations to communicate complex ideas, design innovative solutions, and solve intricate problems. Key Notations and Their Significance: – Basic Symbols (Numbers, Operators, Relations).– Algebra (Variables and Constants, Expressions).– Calculus (Derivatives, Integrals).– Linear Algebra […]

Orifice Plates: Precision in Flow Measurement

Orifice Plates: Precision in Flow Measurement Orifice plates adhering to the global standard ISO 5167-2 are essential tools in process industries for measuring fluid flow in pipelines. But how do they work, and what types are available? An orifice plate, a simple plate with a hole, is placed into a pipe. As the fluid passes […]

Stress Concentration Factors (SCF)

Understanding Stress Concentration Factors (SCF) is crucial in engineering and structural analysis. SCF is a dimensionless factor that reveals stress amplification at specific points like notches or cracks compared to the surrounding material. Why does it matter? The presence of stress concentrations is particularly significant in materials with limited ductility or those prone to fatigue […]

Vortex Induced Vibrations (VIV)

Vortex Induced Vibrations (VIV): The Oscillation Challenge To oscillate or not to oscillate? That, my friends, is the VIV question. When fluid flows past a cylindrical object, it creates alternating vortices that detach from the sides, generating an unbalanced force that pushes the object back and forth. If the excitation frequency of this force aligns […]

Acoustic Induced Vibration (AIV)

Near pressure-reducing devices, such as valves, installed in gas or multiphase systems, acoustic-induced vibrations can occur. When this happens, the phenomenon may cause fatigue failure in a matter of minutes or hours. This phenomenon exists in the high-frequency domain, typically between 300 and 2500 Hz. For thin-walled piping components, this can become a major challenge […]

Flow Regimes Around a Circular Cylinder

Ever wondered how fluid flow interacts with objects like chimneys, bridges, or even power lines? The seemingly simple flow over a circular cylinder is a captivating example in fluid mechanics, with crucial applications across various engineering fields! By understanding how this flow changes with the Reynolds number (Re), a dimensionless ratio of inertial and viscous […]

Performance curves for pumps

Performance curves for pumps are graphical representations of the pump’s capabilities under various operating conditions. These curves typically depict the relationship between different parameters such as flow rate, head (pressure), efficiency, and power consumption. Understanding these curves is crucial for selecting the right pump for a particular application and for optimizing its performance. Here’s a […]

Dynamics of Fluid Sloshing

Sloshing, a fascinating phenomenon, occurs when liquid moves within partially filled tanks, facilitated by sufficient free surface area. This effect is notably observed in marine transportation operations, posing a significant challenge to crack growth of the tanks.  Excitingly, we’ve developed an impressive simulation in-house using #OpenFoam, shedding light on this complex phenomenon. And the CFD results […]

Psychrometric charts and dew points

Psychrometric charts are graphical representations of the thermodynamic properties of moist air. They provide a visual way to analyze and understand the relationships between temperature, humidity, and other properties of air. One important parameter represented on a psychrometric chart is the dew point. The dew point is the temperature at which air becomes saturated with […]
