At Qomaira, we leverage advanced engineering simulation to solve complex design challenges. A critical question in building design, especially for fire-rated partitions, is the choice of insulation. Today, we’re diving deep into a comparative analysis of two common materials: Expanded Polystyrene (EPS) and Rockwool. We used Computational Fluid Dynamics… Read More »EPS vs Rockwool: Fire Safety in Building Design
Problem Description Lowering the temperature of a spectrometer can significantly enhance its performance. Cooling the CCD sensor provides several benefits: Target performance: Our Approach Achieving such a temperature difference is challenging, especially in compact systems. To address this, we combined thermoelectric cooling, efficient heat dissipation,… Read More »Temperature-controlled Enclosure (Design, Simulate, and build)
As wildfires grow more intense, aerial firefighting capabilities must evolve. At Qomalra, we redesigned a helicopter water bucket. We increased its capacity from 900L to 4000L. We also ensured its structural integrity under extreme operational loads. Here’s how we achieved it. The Challenge Existing 900L… Read More »Engineering a Heavy-Duty Helicopter Water Bucket: Scaling from 900L to 4000L
At Qomaira, we recently conducted a performance study. We examined a tunnel ventilation system under both normal operation and emergency fire conditions. The aim was to analyze the interaction between jet fans, tunnel geometry, and air/smoke behavior in critical scenarios. 🎯 Project Goal We need… Read More »🚇 Tunnel Ventilation Performance Under Fire: CFD Analysis & Safety Insights
