Analysis and comparison of the performance parameters of passive and active indirect solar dryers with heat storage facility while drying carrot.

The performance of passive and active convection indirect solar drying systems provisioned with paraffin wax as heat storage was examined while drying carrot slices. The passive indirect solar dryer (type-I) was made initially, and it was upgraded with solar-powered fans to promote mass flow rate. The new assembly was considered an active setup (type-II).

A critical review on solar chimney power plant technology: influence of environment and geometrical parameters, barriers for commercialization, opportunities, and carbon emission mitigation.

Solar chimney power plant (SCPP) is one of the promising technologies to convert solar energy into carbon-free power generation. It has cost competitiveness, environment friendly and longer service life. Although remarkable advancements were achieved, commercialization aspect of the SCPP has not been established so far.

Effect of start of main injection timing on performance, emission, and combustion characteristics of a VGT CI engine fueled with neem biodiesel.

The performance of engine parameters is more influenced with fuel injection strategies namely start of main injection timing (SoMI). An experimental analysis was performed to find the optimum SoMI timing based on performance, emission, and combustion characteristics. Base fuel of diesel and neem biodiesel was used as test fuels.
