Laboratory of the division of Heat and Power Technology
Welcome to the Heat and Power lab, where we conduct cutting-edge experimental research in turbomachinery aerodynamics, aeroelasticity, gasification, combustion, concentrating solar power, energy storage, and polygeneration.
Introduction
Decades of work have given us significant experimental expertise in heat and power. We are the main turbomachinery side research laboratory at KTH and focusing specifically on machines for land-based applications (stationary turbines) and for transport applications (aircraft engines, marine turbines). We have close cooperation outside the institutional boundaries in order to gather expertise from different areas under one roof, thus creating a unique research environment.
Formerly, the laboratory was located in the current Dance School's premises. Since 2005, we conduct our operations in the mechanical engineering quarter. We have an excellent variety of experimental equipment and are the only lab at KTH, which can carry supersonic tests in continuous operation. Our high-flux solar simulator is a unique test facility for Sweden and allows for achieving directed heating of surfaces up to 1500 degrees Celsius for cutting edge research of high temperature solar receivers and related material. We have an infrastructure to handle high pressures and temperatures, a gas system for combustible gases, etc.
Featured Test Rigs
The Laboratory hosts a number of different research rigs related to our research. The test rigs are often operated by the active researchers in respective research group with support of our lab engineers. Some rigs are more permanent, others are developed and operated only within a specific project cycle.

Lab Facilities
Mechanical Workshop
The core facility offers a high level of expertise and services in mechanical construction and manufacturing. The workshops can undertake both mid and small scale tasks in mechanical construction and manufacturing. Workshop is equipped with various machining tools, welding equipment, 3D printers, and mechanical and powered tools for various tasks from prototyping to test rigs production and assembly.
Measurements and test automation
In the laboratory, we have various measurement instruments ranging from multimeters and thermocouples to advanced pressure scanner and process gas analysers. Measuring instruments are typically available on demand for various test activities, but also as components of more test rigs. Test automation is represented by various systems from Siemens PLC to LabVIEW software/hardware interfaces.
Electric Supply
The electricity supply comes into the picture as we need a lot of controlled energy for heating of air flows when simulating flows in gas turbines. Besides the standard 220V/380V, we are directly connected to the 6kV grid and have a large-scale inverter that delivers 140VDC at 6000A current.
Air Supply
The air supply system is the hub of all our wind tunnel testing. We have a broad spectrum of compressors and fans at disposal that we choose based on the experiment in question (low speed, high speed) and requirements on flow and pressure. The velocity span goes from Mach 0.02 to Mach 2.5 and pressure from 0.01 to 40 bar.
