Experimental and computational investigation of waste heat recovery from combustion device for household purposes

Waste heat recovery along with low-grade energy can be utilized for numerous applications in our daily life. This manuscript presents a novel idea of utilizing the waste from domestic cooking devices assisting solar desalination system through simulation and validated experimentally. To assess potential 2D axisymmetric model water jacket has made using ANSYS Fluent while applying user-defined function (UDF) to outermost wall cookstove having temperature as high 340 °C during operation. Further, ensure heat, without affecting performance cookstove, an air gap 0.05 cm was provided between combustion chamber jacket. The efficiency original found ~ 33%, which enhanced up 43.79% flow jacket, finally reached 56% when flows indicates that arrangement used this particular study not only recovered but also improved overall by 69.34%, disturbing phenomenon.
