Cooling and air-conditioning systems: testing performance of systems. pressures, temperatures, power with changes of parameters such as heat absorption and heat release rates in heat-exchangers. Operation of a system as a heat pump. Experimental bearing systems: run-in of a glide bearing under loading condition under variable speed and obtaining the pressure distribution around the bearing perimeter and along its axis.

Measuring parameters, such as pressure distribution along the nozzle, flow-rate, effects of pressure variations of the entrance and at the exit. System of flow-rate gauges in pipes: inspection of the flow-rate gauge performance in a nozzle. Venturi-gauges, orifice, inspection of pressure gradients along pipes with different characteristics.

Experiments with a cylinder in a wind-tunnel: inspection of pressure distribution around a cylinder in sub-sonic flow. Calculating the acting forces and measurements in a wake. Flow in converging-diverging nozzle. Obtaining the speed-profile and mapping the flow in the nozzle. Experiments in a water tunnel: channel flow, hydraulic jump, flow through converging-diverging channel and analogy to the transition from super-sonic to sub-sonic flow. Heat exchager: examining the performance of a heat exchanger. Opposite and parallel flow. Cooling tower - its performance as a function of fundamental parameters, such as: liquid flow-rate, size of drops, air flow-rate and room conditions, temperature and humidity. Turbulent jets: measuring mean velocity-profile and turbulent fluctuations in a jet by hot-wire anemometries and Pitot tube. Diesel engines; measuring typical parameters, such as: thermal efficiency and specific fuel consumption in four-cycle Diesel engines with one cylinder.
