Free Engineering Simulation Tutorial - Opensource Software & Simulation Guides

Ever sat in a project meeting where the HVAC consultant rattles off "we need 120 TR, 40,000 CFM at 2 inches static" — and half the room quietly nods without a clue? HVAC is full of jargon that MEP consultants use daily but owners, architects and clients rarely understand. This guide fixes that: a plain-English glossary of the most important HVAC terms so everyone can follow the conversation — plus a free HVAC Unit Converter for the conversions consultants do constantly (TR ↔ kW, CFM ↔ m³/hr, inWG ↔ Pa, and more). Table of Contents The HVAC Unit Converter Why These Terms Matter Cooling Capacity Terms Airflow & Pressure Terms Equipment Terms (AHU, FCU, VAV…) Efficiency & Heat Terms Quick Conversion Table FAQ The HVAC Unit Converter Pick a category, type a value, and get the converted result instantly. Built for the imperial↔metric conversions MEP consultants use every day.  HVAC Unit Converter C...

MATLAB Heat Transfer Simulation: Conduction, Convection & Radiation MATLAB Heat Transfer Tutorial · Conduction · Convection · Radiation · Thermal Analysis · Engineering Simulation MATLAB heat transfer simulation is a useful way for engineering students to move from equations on paper to a numerical model they can inspect, modify and validate. In this tutorial, we build a practical steady-state thermal model covering conduction, convection and radiation . The complete MATLAB script calculates the three modes, solves a combined wall problem, produces seven engineering plots and checks the final energy balance. The example is deliberately small enough to understand without a large CFD package, but it still introduces professional numerical habits: clear inputs, SI-unit consistency, a nonlinear energy balance, numerical root solving, parameter sensitivity and validation. You can run the supplied .m file first and then change the inputs to turn the article into a hands-on labo...
